Bending moment and solid elements

[Chicca96]

Good morning,
I would like to apply a bending moment to a beam modelled with solid elements. However, solid elements have only ux, uy and uz DOFs.

Actually, I’m interested in the stress stae caused by the bending moment and I have also tried to apply it to each node using the “sf” command. Unfortunately, I did not obtain the correct result.

Is there a way to solve this problem?

Thank you for your time and help.

You probably need many solid elements thru the thickness to get close to the correct bending stresses.

Have you read the manual for your FE software? Most major code manuals have beam test cases results for many of their common elements.
