Conference Sessions

Sessions confirmed so far are listed below.

All session titles are preliminary.

Reliable, generally accepted, and - if possible - easy-to-apply calculation guidelines for providing proof of safety and thus preventing failure processes are not only very helpful for the developing engineer but are absolutely indispensable against the background of increasingly stringent safety requirements.

The presentation of innovations in the field of guideline developments and their application are the subject of this session. Equally, contributions that demonstrate the practical benefits of the guidelines by presenting the experiences of industrial users are highly welcome.

The target groups are engineers from all branches of mechanical and vehicle engineering and aircraft construction as well as plant and apparatus engineering who are active in the test field, in development, design, and calculation as well as monitoring and maintenance of machines and plants in industry and research institutions.

Suitable joining technologies are essential for efficient lightweight structures made of fibre-reinforced composites. In the design process of such joints, failure mode and strength, both under quasi-static and dynamic load, are crucial information. This session will therefore focus on analytical and numerical calculation methods for predicting damage initiation and progression under different loads, e.g. impact, fatigue and (residual) strength. Experimental work that is intended to validate the calculation methods is also welcome. Work that addresses the circular economy, for example the modelling and simulation of detachable bonded joints, is especially encouraged.

In modern engineering, lightweight structures offer numerous advantages in terms of efficiency, sustainability, and performance. However, their design and implementation come with inherent challenges related to structural integrity and resilience. This topic explores various strategies for mitigating failures in lightweight structures, focusing on both proactive design approaches and reactive measures. Proactive strategies include advanced materials selection, innovative structural configurations, and optimization techniques to enhance strength-to-weight ratios while minimizing vulnerabilities.

Additionally, incorporating redundancy and robustness principles into design frameworks can bolster resilience against unexpected loads and environmental conditions. Furthermore, integrating sensor technologies and real-time monitoring systems enables early detection of potential failure modes, facilitating timely intervention and maintenance actions. Reactive measures encompass damage-tolerant design principles, such as fracture mechanics and fatigue analysis, to predict and mitigate failure propagation.

Moreover, implementing adaptive control systems and self-healing materials offers promising avenues for enhancing structural resilience and prolonging service life. By adopting a comprehensive approach that combines proactive design strategies with reactive interventions, engineers can effectively address the challenges of failure mitigation in lightweight structures, ensuring enhanced performance, safety, and sustainability across various applications.

Fracture-mechanical properties of materials in micro- and nanoscale dimensions have become an important area of fundamental research, including the development and introduction of new techniques for micro- and nanomechanical testing as well as for high-resolution 3D imaging of features in opaque objects.

Building structures are exposed to many unforeseen risks due to environmental factors, human error and unexpected impacts. The vast majority of these lead to extensive structural damage that prevents safe further use.

The session covers all issues related to the analysis of failure in engineering structures with their effective protection. 

Effective protection of building structures can be implemented in two groups of activities:

  • The first includes preventive actions that counteract the effects of possible risks or removing minor damage that has already occurred. In this way, more significant damage is prevented and the threat of a major accident or catastrophe is eliminated.
  • The second group of works includes repair and strengthening of already damaged structures to enable their continued safe use. In order for the applied actions to be effective, it is necessary to properly identify the causes of the observed problems, which makes it possible to eliminate them and, only then, to select the correct preventive works or repair methods.

Sustainability challenge demands for structural fibre-reinforced composites in mass applications: -transports (automotive and collective) aiming at weight reduction (higher specific strength) and increased safety (e.g. fire resistance); constructions aiming at higher durability, using fibres for repairs and instead of steel; offshore renewable and wind energy production; hydrogen storage and exploitation (e.g. Ceramic Matrix Composites in hard-to-abate productions). Carbon neutrality target imply Polymeric Matrix Composites: -developing sandwich structures; -exploiting biobased fibres and resins whenever possible; -produced and recycled cheaper, faster and with less energy-demanding processes; -based on semifinished raw materials that (ideally) do not require storage at low temperature. Mass production sustainability also requires: -composites recycling, circularly reusing both fabrics and resins as much as possible; increased durability and easier repairability; - reduced use of glues and ecodesign of multimaterials and systems aiming at full recovery of each original raw material; reducing the use of gelcoats and paints (primary source of microplastics), PFAs and other dangerous chemicals.

The considerable transformative capacity inherent in additive manufacturing (AM) to revolutionize conventional production methodologies is widely acknowledged, particularly in the realm of fabricating intricately designed components utilizing materials historically presenting challenges in machining, such as superalloys. The recognition of AM's profound potential to reshape future designs, wherein its capabilities are leveraged to fabricate metal components with sophisticated geometries, is steadily gaining momentum. Consequently, there exists a current emphasis on investigating diverse facets of various AM technologies, with the objective of advancing scientific understanding and facilitating their integration into industrial frameworks.

The substantial investments in time and research endeavors have engendered continual advancements across the spectrum of AM, fostering a burgeoning sense of optimism concerning the widespread adoption of AM methodologies for the manufacturing, repair, and overhaul of metal components. These imperative underscores the necessity to showcase these notable advancements, thereby catalyzing the proposition for a ICEAF conference session in Materials, dedicated to illuminating state-of-the-art developments in the AM of metallic materials.

Recent technological developments establish additive manufacturing (AM) technologies more and more amongst the favourite physical processing routes for producing complex shapes, multi-material components and functional materials. Variations in physicochemical and mechanical properties of additively manufactured products originate mostly from surface conditions, defects, feedstock and build anisotropy. These properties affect the structural integrity, physical and in-service performance with respect to corrosion, fracture, mechanical, functional and wear behaviour. Additive manufacturing is often followed by post-processing, such as heat treatments and hot/cold isostatic pressing, which would also influence/alter the microstructural features and subsequently the mechanical behaviour, physical / functional properties and structural integrity of the material.

The aim of the session is to improve the understanding of the processing-structure-properties relation of additively manufactured materials as compared to materials produced by conventional processing, such as casting, rolling, extrusion, forging, etc. Emphasis will be given on the effect of process parameters on the microstructure, surface conditions, material texture/anisotropy and mechanical/environmental and functional behaviour.

Simulation based on computational solid mechanics models describe the response of structures, as a function of their geometry, loading, boundary conditions and material behaviour. Digital Twin Validation i.e. 'the process of determining the degree to which a model is an accurate representation of the real world, from the perspective of the intended uses of the model', is of the most important aspects of engineering simulation. It is the responsibility of the digital twins users to perform sufficient validation of the models developed, by reference to experiments specifically designed for this purpose. Optical measurement and other relevant experimental methods have reached to a sufficient technology readiness level that enable displacement or strain data over large areas or even the entire structure to be reliably  captured during an experimental test and thereafter visualized and analyzed. Such developments have provided the background for a more comprehensive approach to model validation used in engineering design and evaluation of structural integrity, which could lead to optimized and less conservative designs. During the session, important recent advances on simulation model development and validation methodologies will be presented by researchers from industry and academia, focusing on validation of novel aircraft structural components and structural details.

Crashworthiness is the capability to leverage the controlled failure of a structure to dissipate the kinetic energy of an impact, thus protecting occupants of vehicles and valuable equipment. Composite materials exhibit unique behavior in terms of local strength, energy absorption, and failure modes with exciting potential in airborne and ground vehicles’ crashworthy structures.

In this context, progressive failure analysis plays a pivotal role. Controlled brittle failure in thermosetting fibre-reinforced polymer composites offers efficient energy absorption mechanisms, making them attractive for crashworthy vehicle designs. However, their performances depend on several design factors, such as material constituents, stacking sequence, and component geometry. Numerical simulations have proved to be a valid tool to analyse the effect of these parameters and streamline the design phase, reducing costs and time to market. Nevertheless, material calibration is a critical step in implementing reliable numerical simulations.

  • Impact behaviour of composite structures
  • Theoretical modelling for composites under dynamic loads
  • Numerical methods and virtual testing for composites under dynamic loads

Very often based on lessons learned from aircraft accidents, design methods and processes for compliance demonstration with applicable standards have been established that are able to increase the level of safety for the occupants of an aircraft. The topic of the session covers new solutions to the “classic” structural design aspects for crashworthiness, such as structural integrity and energy absorption characteristics of the airframe, efficient restraint systems, minimized environmental hazards from loose or sharp objects, and reduced post-crash hazards from fire, smoke and fumes.

Artificial Intelligence (AI)/Machine Learning (ML) is playing an increasingly important role in the design, manufacture, and failure analysis of materials and structures. This session will focus on the use and development of AI/ML approaches to enhance our ability to design and analyze advanced materials such as metamaterials, composites and alloys, or to accelerate the manufacturing process and subsequent failure analysis. Contributions on optimization of material properties, acceleration of materials/structures discovery, and AI-driven manufacturing of new materials/structures as well as failure analysis are very welcome. Experimental and methodological contributions involving the use of AI/ML in this context are also welcome. 

The aim of this symposium is then to bring together leading experts from materials science, mechanics, artificial intelligence, and other related fields to promote research in this emerging field and foster cross-disciplinary collaboration and innovation.

This session aims to cover, but is not limited to, the following issues:

  • Data-driven design of metamaterials
  • Machine learning based composite design and inverse design
  • Computational methods and information processing
  • AI-assisted fractography of alloys and materials
  • AI-assisted manufacturing
  • Machine learning based fatigue life prediction
  • Modelling and optimization in metallurgical design
  • Application of new materials/structures
