Abstract

The structures in service are subjected to loads whose amplitude varies most often over time. These differences in loading cycle levels will have a direct impact on the propagation of cracks that can lead to accelerations or slowdowns in the propagation speed of these cracks. Indeed, the delay of the propagation of a crack produced by the application of a simple overload depends on several parameters, such as the material, the loading, the geometry of the specimen and the environment. In this paper, we will try to master more light only on the influence of the loading parameters such as the load ratio, the overload rate on crack propagation, the propagation speed, the number of delay cycle, using the AFGROW calculation code and the willenbourg model, which describes the delay after applying overloads.
