Conference Sessions

Sessions confirmed so far are listed below. The list is continuously updated. The classification of the sessions in technological areas will follow.

Considering the latest developments in all the industrial sectors and the need for advanced and sophisticated composite structures, this section deals with the manufacturing processes for producing reliable composite structures with minimized defects content. It covers a large variety of manufacturing procedures, among which the thermoforming, injection molding, filament winding, wet molding, lamination, pultrusion, automated tape layering, aerosol jet printing etc., as well as a combination of them. Quality assessment, defect detection, mechanical characterization, and simulations towards the neat amelioration of the outcome of the fabrication process are expected in this session, aiming to go a step further to the so-called zero-defect manufacturing of composite materials and structures.
 

Structural Health Monitoring (SHM) methods and architectures for damage detection and localization in structural components and assemblies (metallic, composite or hybrid). Techniques based on analytical or/and numerical modeling procedures. Statistical pattern recognition and Machine Learning based methods. Uncertainty quantification in the SHM problem accounting for environmental and operational variability. Approaches for generating structural digital twins. 
 

The correct treatment of the size effect is an unavoidable requirement to ensure safety of the components and structures. Interesting advances have been achieved in the size effect when FEA applications to face the complex cases raising in the current design. This, in turn, poses new challenges to be resolved due to the complex cases that are being presented in practice.

The concept of structural integrity requires a consistent use of probabilistic assessment techniques to achieve a reliable characterization of materials and components and their application to the failure (fracture and fatigue) design of components and structures.

In this session, contributions from engineers, scientists, consultants among others are expected contributing to the development and applications of models related to the probabilistic evaluation of experimental failure results, particularly related to size effect. The session will be a suitable forum to discuss the last advances on size effect and probabilistic fatigue assessment studies allowing a multidisciplinary discussion to be achieved.

Additive manufacturing (AM) techniques offer a disruptive transformation in how products are designed and manufactured. The direct conversion of digital geometries into physical parts translates into less waste of time and material compared to traditional manufacturing processes. This peculiarity combined with the impressive evolution of AM technology has allowed the production of complex parts for different engineering applications and has positively impacted the overall economy, owing to the potential use of AM for prototyping, production, and repairing. Presently, it is used in many industries, such as aerospace, defense, automotive, consumer products, industrial products, medical devices, and architecture. In order to take full advantage of AM, understanding and estimating the mechanical performances of the related parts in load-bearing applications is of paramount importance. The structural integrity of AM parts is therefore a key topic to be investigated for supporting the spread of this technology. The special session entitled “Fatigue and Fracture of additively manufactured materials and components” will focus on the relationships between process parameters, post-fabrication treatments, microstructure, surface state, and statistics of defects. 

Interest in additive technologies has grown swiftly as applications have progressed from rapid prototyping to the production of end-use products. Additively produced components can now use metals, polymers, composites, or other powders to make a range of functional or daily usage components, layer by layer, including complex or "lighten" porous materials that cannot be manufactured by other means. Despite much research and the results achieved, however, there are still unexplored problems in this area that cause components produced by the additive approach to fail in operation or after a short period of their use. The objectives of the session are therefore focused, but not limited on 

  • Influence of manufacturing/technological conditions on the quality of 3D printed parts
  • Mechanical properties of additively produced samples/components
  • Analyses and simulations
  • Failure/fracture modes and criterion
  • Failure prediction and prevention
  • Testing and defects detecting
  • Application of AM parts in real practice
  • The behavior of cellular materials and structures (their properties, manufacturing, testing, etc.)

Recent technological developments establish additive manufacturing (AM) technologies more and more amongst the favourite physical processing routes for producing complex shapes and multi-material components. 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 and in-service performance with respect to corrosion, fracture, mechanical 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 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 behaviour. Processing simulations and (micro) structural modelling are necessary to verify the performance of AM materials and products. Abstracts may thus refer to experimental and/or modelling studies relating various aspects of processing, microstructures, properties and performance of additive manufactured materials or components.

This session welcomes a broad spectrum of studies that are addressing aviation industrial problems, not the least of which are related to a pressing demand for optimization and automation as well as a broader sustainability agenda. The subjects include but are not limited to: Advancements/Innovations in Maintenance, Repair, and Overhaul (MRO), Aircraft systems health monitoring (SHM), Condition-based and predictive maintenance (CBM/PdM), MRO Decision Support Systems, Emerging inspection/NDT and repair methodologies, Advanced aerospace materials, Novel propulsion solutions.

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. Beyond these traditional crashworthiness considerations, and in view of new trends in aircraft design, the session also includes novel features of innovative propulsion systems and propellants such as electrical, mechanical, chemical, and functional safety of electric power trains or fuel cells and the storage and on-board handling of hydrogen. Finally, the session is also open to operational aspects, for instance, recovery systems or human factors.

The process for the design of materials and devices is aimed at defining a nominal set of input parameters to achieve given performances in operating conditions. Nevertheless, the realization of the final product eventually results in an imperfect component, which can be low-performing or even fail to meet the requirements, due to the unpredictable effect of variables that intervene in the fabrication process (e.g. geometrical tolerances of the design parameters, fluctuations of the environmental conditions, variations of process-dependent quantities).
For this reason, several analytical, computational, and experimental approaches exist with the multiple purpose of assessing the impact of tolerances on selected quantities of interest, understanding t the most influential parameters, and determining the nominal set of parameters ensuring robust performances of the designed material or device with respect to uncontrollable fabrication-related variations.


This specials session welcomes contributions concerning the theoretical and experimental techniques adopted during the design phase of materials and devices to take into account the uncertain parameters, aiming at assessing the sensitivity of the component and achieving its robust design.

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.

The session entitled "Recent advancements in welding processes " aims to cover the following topics:

  • Phase transformations in weldments, microstructure-property relationships
  • Solidification
  • Sensing, control, and automation.
  • Residual stresses and distortions: measurements, modeling, and mitigation
  • Welding practices in industries
  • Weldability of materials
  • Weld failure modes & Design criteria  
  • Failure analysis of welded structures 

Prolonging the service life of engineering structures by protecting against influences from aggressive environments is a challenging industrial need. On top, circularity of materials supporting the new paradigms of the European green deal calls for new material concepts covering the complete life cycle of parts.
This session is open to scientists and engineers working in applied research in the field of materials development and surfaces technologies designed to avoid corrosive degradation and damage. Aspects of protective coatings development and modelling, including aspect of recyclability and sustainability, builds a special focus of the event. 
Contributions on new approaches and results in materials modeling, optimization, business decision support systems and digitalization, as well as characterization methods (both destructive and non-destructive) applied to corrosion engineering and surface protection technologies are very welcome in this session.
