The beam is bended. Maximal stress and strains are on both surfaces (top and bottom). Plasticity is reached at these locations while the core is still elastic.
Do you know GMSH? Do you know how to make hex elements in GMSH? I have not been successful with this.sodelo wrote:With tetrahedra, having a fine enough mesh often means having a hell of a big mesh
With hexahedra, 1st they are more accurate and second, you can cheat and get your fine elements only in the direction you are interested in.
