Abstract : The problem to be considered is the analysis of rectangular, laminated, fiber-reinforced plates. The loading condition are assumed to consist of normal pressure applied to one lateral face, arbitrary edge forces and moments applied to the edges and a uniform temperature distribution. Internal boundary conditions involve the continuity of the three components of the displacement vector and the components of the stress vector normal and tangent to the individual plies. Assuming that the primary interaction is between plies, the plate is modeled as a laminated plate for which each ply is assumed to obey a stress-strain law with twelve independent elastic constants and three independent coefficients of thermal expansion. These local properties are assumed to vary discontinuously from ply to ply. Internal continuity conditions at ply interfaces can be identically satisfied by an integral formulation of three-dimensional stress function theory.
