A Note on Generating Generalized Two-Dimensional Plate and Shell Theories.

摘要

Ordinary two dimensional linear shell theory may be formulated using six differential equations for stress resultants and couples and for middle surface force and moment load intensities, in conjunction with the principle of virtual work for the derivation of strain displacement relations. The present paper deals with a more general formulation, involving additional two-dimensional equilibrium equations, as a consequence of three-dimensional equations for force and moment stresses in conjunction with a stipulation of surface force and moment load intensities for two face surfaces.
