Hi everybody

I'm doing my final degree work of mechanical engineer in Málaga university (south of Spain). This is the efect of the shear force in the bending of a sandwitch beam. I mean the effect of tranverse shear strains,neglected in the classical theory (Euler-Bernoulli theories) becomes significant in sandwitch beams.

I have to study by hand calc and by modeling by a FEA software. I have recently done a course in Comsol (30 hours) at the University,but i dont know how mesh and the boundary conditions. I try a lot but the reults are not corrects.I need to use brick elements (hexaedro).
Can you give me some advice?
Please see the attachment file.

Thank you in advance and sorry for my limited english.
