There can be also surprisingly large inaccuracy when fully integrated beam elements are used with plasticity and when the mesh of beam elements is not significantly refined:
Hi,
I am currently working on the following scenario - a cantilever beam (rectangular section) meshed with solid elements subjected to a concentrated force at the free end. Bending occurs in the elasto-plastic regime (elastic perfectly-plastic material model). My goal is to obtain the deflection as close to the analytical one as possible using solid elements. Here are the current outcomes:
analytical solution: 23,625 mm
beam elements in Abaqus (40 x B22): 23,69 mm
solid elements in Abaqus (70…
