Residual stresses in engineering structures are caused by a variety of different mechanisms including manufacturing and joining methods and can dramatically influence the failure behaviour of materials. They can change the crack initiation, crack growth and fracture as well as affecting the wear, corrosion etc. It is known that, in general, tensile residual stresses have detrimental effects and compressive residual stresses are beneficial. Therefore, for integrity assessments of engineering components, it is important to obtain a detailed knowledge of residual stresses.
This session aims to gather research outcomes on failure when combined with residual stresses and offers an engaging exploration of current insights on qualifying / quantifying the effects of residual stresses on failure. It provides a platform for sharing expertise at macro or micro levels of any failure mechanism when residual stresses are contributing. It also aims to gather research papers on the life predictions models and life extension methods where residual stresses are considered. Papers on the measurement of residual stresses are also considered.
