Modelling in Fatigue Remarks on Scales of Material Description: Application to High Cycle Fatigue

  • K. Dang Van
Part of the NATO Science Series book series (NAII, volume 32)


Fatigue failure is the final step of complex physical processes difficult to model: It begins with the appearance of slip bands in some grains which broaden progressively during the following cycles. These phenomena occur simultaneously with the development of localised damage. The processes result in the formation of intragranular microcracks at a stage determined by the imposed load level. After a certain number of cycles, a main crack initiates, then propagates and shields the other defects and, consequently leads to a the final rupture of the mechanical structure.
