ST7-18.104.22.168 Nonlinear Stress vs Strain Curves for Beam Elements
The Strand7 beam element is the most flexible element in terms of the nonlinear material behaviour it supports. Similarly to the plate and brick elements, the beam element supports both nonlinear elastic and elastic-plastic material behaviour. Unlike the plate and brick elements, the beam element also supports elastic-plastic behaviour that is different in tension and compression (plates and bricks support different tensile/compressive behaviour only for nonlinear elastic materials).
This Webnote summarises the usage of Stress vs Strain tables for beam elements.
