Hello everybody,

                          I am trying to perform a harmonic analysis of a material sample (say a simple 2D plate) with an edge crack in it using 'Ansys R16'. I see that under sinusoidal loading condition, the two crack faces open or close and interpenetrate (after closing which is not possible practically).

Hello everybody,

                   I am working on FE Simulation of interface cracks. To this end, I use modified VCCT, CSDEM and other such methods to determine mesh independent strain energy release rate (G) and Mode mixity (ψ). Now I have a fundamental doubt.
