Instable Crack Propagation Analysis with PDS-FEM
This paper studies the stability of dynamic crack propagation in a homogeneous plate with 2 parallel cracks located in an anti-symmetric manner. PDS-FEM is extended to the dynamic setting, and a method to randomly generate unbiased mesh is developed. Monte-Carlo simulation is carried out to study the crack patterns. It is shown that a solution for low and high loading rate displacement loading condition is stable or instable, respectively, since the crack pattern loses anti-symmetricity for the latter boundary condition.
