This symposium will focus on the latest advancements in fatigue evaluation, integrating experimental, computational, and analytical approaches across multiple length scales.
Topics include fatigue behaviour in metallic alloys, shape memory alloys and multi-materials, as well as the role of defects and residual stress in fatigue performance. The influence of manufacturing processes on fatigue is also of interest, particularly focusing on those currently under development, such as additive manufacturing, as well as more established ones, joining processes, casting, etc.
Contributions on a wide range of fatigue regimes are encouraged, encompassing low-, high-, and very-high-cycle fatigue, fretting fatigue, thermal fatigue, and creep-fatigue. Multiaxial fatigue stress states, variable amplitude & vibration fatigue are equally welcome.
Computational and analytical methods for modelling fatigue damage at different length scales are welcome, including those based on Finite Element Methods (FEM), Crystal Plasticity FEM (CP-FEM), cohesive approaches, phase-field, and others.
Special emphasis will be placed on current advances in probabilistic methods for fatigue evaluation, including those based on machine learning, physics-informed machine learning, and artificial intelligence in general.
Advances in fatigue testing systems and characterisation methods ranging from the metre down to the nanoscale will be welcome.
Failure analysis, fatigue damage monitoring, and micro-/nano-mechanical devices and systems (e.g., MEMS, thin films, etc.) will also be explored. The symposium aims to promote interdisciplinary discussions on improving fatigue assessment and predictive capabilities across engineering applications.
