Hello everyone,
I just started learning CalculiX and need help.
I want to simulate the deformation of paper.
Paper consists of fibers and is anisotropic. Is there any way to calculate plastic deformations of an anisotropic Material wird CalculiX?

Unfortunately, there’s no anisotropic plasticity (Hill potential) in CalculiX, you would need UMAT subroutine for that. But layered composites with different ply orientations and anisotropic elasticity are supported. By the way, paper is considered to be auxetic.
Also TFEL/Mfront is not deal to implemented, however an orthotropic plasticity is available there.
