Description

Typologically sheets can be regarded as a plate case generalization. The non coplanarity conferred by the geometric approach of the shell by plates permits the existence of axial forces (membrane forces) which, together with the bending effects, contributes to provide the foil bearing capacity higher than plates. SHELLS is the set of programs that apply the finite element method to the flat sheets calculation based on the plates ‘s classical theories.

Some structures that can be analyzed are: bridges, decks, tanks, ship hulls, aircraft fuselage, vehicle bodies, etc.
