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).
1. I believe, stiffnesses of the crack faces change during interpenetration and so the results are not credible anymore.
