Abstract
Based on the generalized thermoelasticity with two thermal relaxation times (G-L theory), the mechanical parameters through the zero-impedance interface in a laminated plate under transient thermal shock, such as the displacement, stress and temperature, are studied by using the finite element method. The displacement, stress and temperature near the interface of the composite plate are obtained. With the influence of specific heat capacities, heat conduction coefficients, thermal relaxation time and densities of two materials, it is found that the displacement and stress through the interface of composite plate has a sudden change. The results are useful to obtain the deflection of composite plate caused by heat.
