Multi-linear plastic material. This is the more advanced option than the bilinear material described previously. A lot of settings remain the same (yield criterion, hardening rule, initial yield point). Instead of work hardening slope H, you have to define a curve showing the multilinear relation between stress and strain.

Nettet7. mai 2024 · So naturally, if you input a material non-linearity, there are higher chances that you will face convergence problems. Lower tangent modulus (in the strain hardening region that you have inputted as a bilinear plastic model) actually renders the elements to have increased vulnerablity to element distortion during solution. Nettet6. okt. 2024 · The Tangent Modulus for a material with Bilinear Hardening (such as the one here) is the slope of the curve beyond the yield stress. In the plot above, the first line with a high slope has a slope of 2E11 Pa (i.e. slope is equal to the Young's Modulus).
