Tóm tắt

The classical field and boundary equations governing the in-plane stretching and the transversal bending of a thin plate are obtained by means of an exact mathematical procedure consisting in integrating over the thickness the equilibrium equations for a three-dimensional cylindrical body, made of a homogeneous, linearly elastic, transversely isotropic material, and subject to suitable internal constraints.
