Congrès

LCF9 Ninth International Conference on Low Cycle Fatigue

context

The permanent and even growing interest of the scientific community in lowcycle fatigue, including thermomechanical fatigue addresses on the one hand a broad range of applications, e.g. in energy technology, transportation, civil engineering, and several other topics. On the other hand, many scientific questions on fundamental deformation and damage mechanisms, influence of multiaxial stresses / strains, creep-fatigue and TMF/HCF interaction as well as crack initiation and growth are investigated with increasing experimental efforts.

As a bridge between fundamental research and application in component and structural design, simulation approaches for cyclic plasticity, crack initiation and growth have made impressive and still continuing progress in the recent decades: FEM-based deformation and life assessment models at different scales, from the microstructure to macroscopic structures, are state-of-the art and under further successful development, especially for reliable design of components undergoing complex thermomechanical loadings. Current research activities show that LCF research keeps being a hot topic in material research and in structural integrity considerations as well.

This development is augmented by the current megatrend in digitalization imposing new challenges in data acquisition and storage in appropriate database structures as well as in data processing and usage of cloud computing approaches in fatigue research which is a-priori associated with handling big data volumes in experiment and simulation. The increase in 2D-3D full-field measurements by image-volume correlation associated to high-fidelity FEM simulations are a major challenge in this context.
