Tips and Tricks #1405: OptiStruct – Membranes in LGDISP & Plasticity

Membranes are supported now for LGDISP NLSTAT analysis.For Nonlinear materials, plasticity is supported for membranes– both SMDISP and LGDISP.Both 1st order and 2nd order elements are supported for SMDISP and LGDISP NLSTAT.Stress on membranes should be comparable (not exact) to surface stresses on solids (which can be obtained with specifying ISOP option as INT0 in PSOLID, and output stress at GAUSS location).
