Dynamic Stress Intensity Factor Computation by Using Xfem Formulation

Abstract:

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 two different techniques, namely the technique of displacement jump and that of interaction integral. A comparison between the two approaches is discussed. Moreover, the effects of crack orientation and damping material on the DSIF variation are tested. The good correlation of the obtained results for the treated examples with the literature ones demonstrates the effectiveness, accuracy and robustness of the computer software developed in this study.
