Convergence Problem with orthotropic material
I am performing a Tensile test for a thin fabric with Orthotropic properties. I turned on large deflections to get non-linear behaviour & also took around 500 initial substeps & 50 min. substeps but it doesn't converges and nodes gets distorted on the fixed end. The same i performed for Structural Steel and i got the desired result. Can anyone please help why this convergence problem is arising for orthotropic materials & how to get the convergence right?
