Nonlinear Material Law for Membranes

Product Feature

In RFEM, there is an option to couple surfaces with the stiffness types "Membrane" and "Membrane Orthotropic" with the material models "Isotropic Nonlinear Elastic 2D/3D" and "Isotropic Plastic 2D/3D" (RF-MAT NL add-on module required).

This functionality enables the simulation of the nonlinear strain behavior of, for example, ETFE foils.
