Thermal bending analysis of laminated orthotropic plates by the generalized differential quadrature method

The interlaminar stresses in a thin laminated rectangular orthotropic plate with four sides simply supported edges under bending was determined by usi ng the generalized differential quadrature (GDQ) method involving the effec ts of thermal expansion strain and transverse Load. The approximate stress and displacement solutions are obtained under the effects of thermal expans ion force and uniform pressure load for eight-layer unidirectional laminate s, symmetric cross-ply laminates. Numerical results on the dominant interla minar stresses and displacement of bending analysis are compared to the Nav ier solution. The thermal induced forces have significant effect on the ben ding of plates.
