Numerical Calculation Method for Crack Dynamic Propagation Based on Newmark Implicit Time Integration Scheme
Extended finite element method (XFEM) is based on the idea of unit decomposition. The jump function that can reflect the discontinuity of the crack surface and the progressive displacement field function of the crack tip is added to the conventional finite element displacement mode, which avoids the...
