Thermo-elastic analysis of simply-supported orthotropic laminated beams subjected to high temperature and mechanical load is presented on the basis of the exact two-dimensional thermo-elasticity theory.The beam is composed of several orthotropic layers,each with temperature-dependent material properties.The goving equation for each layer is analytically solved using the state space method.The displacement and stress solutions of the beam are obtained using the transfer-matrix method.A numerical example is included to study the effects of temperature on the mechanical responses of a sandwich beam.The results reveal two main effects of temperature:(i) inducing deformations and stresses by itself;(ii) affecting the deformations and stresses induced by the mechanical load.
