Has anyone tried to use the Duncan Chang Model for 2D model in comsol multiphysics? Could anybody send me an example? i did find it under nonlinear elastic material but could not successfully implement it.
I'm trying to install abaqus on manjaro Linux but have been unable to do so. In the Linux.sh file I commented out the DSY_OS_Release=`lsb_release --short --id |sed 's/ //g' line and replaced it...

I need to model an anisotropic material in which the Poisson's ratio ν_12 ≠ ν_21 and so on. Therefore, the elastic compliance matrix wouldn't be a symmetric one. In ANSYS APDL, for TB,ANEL...
