Is this value be the yield strength of the material or the maximum equivalent von-mises stress when the static structural analysis is performed prior to topology optimization?<\/p>\n<p> I am doing the stress constraint topology optimization of the L-shaped beam structure with the material is considered as aluminum alloy and the fixed constraint is applied at the top and point load of 1500 N is applied at its tip. The model is modeled as surface and the analysis is kept 2D(plane stress). The length is 200 mm and width is 80 mm. The point load is applied as nodal force and distributed to some nodes so as to avoid the stress concentration and the 4 noded quad elements are used.
