Abstract
An isoparametric finite element formulation is presented for thermo- structural bending analysis of composite plates. In the thermal phase both steady and tran sient states are analysed, taking into consideration conduction, convection, and radiation heat transfer modes. Externally varying heat fluxes and internal heat generation sources are also considered. The non-linearity in the heat equation arising out of the radiation boundary condition is tackled with the help of a modified Newton-Raphson procedure in conjunction with the Euler backward difference implicit time integration scheme. The structural model includes the bending-stretching coupling and the effect of transverse shear deformation. In the numerical analysis a square metal matrix composite cantilever plate is assumed to experience a heat flux encroaching progressively inwards from the free end. The performances of two metal matrix composites in the same situation are com pared.
