Modeling of cracked structures containing voids subjected to fatigue and dynamic loads using XFEM
In this paper,we present a modeling of planar structures under dynamic loading containing stationary cracks in order to determine the dynamic stress intensity factor (DSIF).This parameter will be evaluated by using the eXtended Finite Element Method (XFEM) coupled with the interaction integral technique.Some examples of validation of the computer code developed in this work were tested.The good correlation of the obtained results in fatigue with the literature proves the effectiveness of the method as well as the developed computer code.In the dynamic case,a parametric study on the presence,position and size of the void with respect to the crack and also on the crack type (crack edge and central crack) was conducted for some practical applications.
