Crack Path in VHCF regime

Keywords: VHCF, Crack Path, Experiments, Modeling, Numerical simulation
Fatigue and fracture are considered main causes for in service failure of mechanical components and structures. The need for the weight reduction of components and a growing need for greater lifespans of equipment, forced the understanding of the fatigue behavior of materials under an increased number of loading cycles.
This symposium aims to assess the current knowledge about crack paths in Very High Cycle Fatigue (VHCF) regime or at very low crack growth rate, and to evaluate the crack path under different loadings (tension, torsion, multiaxial loadings) on several materials, environments and boundary conditions. Furthermore, papers on test of components and testing machines to perform uniaxial, biaxial or multiaxial fatigue tests in very VHCF domain are welcome whatever the material: metallic alloys, composites, etc..
Regarding VHCF several issues (frequency effect, strain rate, temperature effect, environment, loading control, …) need more investigation. The main objective of this Symposium is to bring together researchers, engineers, and students to present and exchange recent data and new ideas, allowing an interesting multidisciplinary discussion.
