英文摘要	To investigate the generalized thermoelastic dynamic response of a sandwich plate subjected to symmetrical thermal shock, assuming that the value of thermal impedance at the interface is zero with ideal adhesion and the material properties change with the temperature, the governing equations of the layered plate with generalized thermoelasticity coupling are formulated based on the fractional order generalized thermoelasticity theory. The governing equations are solved based on Laplace transform and its numerical inversion, and the numerical values of the non-dimensional temperature, displacement, and stress are obtained. The effects of material parameters alteration including the thermal conductivity, density and heat capacity at the interface on the heat transfer and structure response are studied, and the effects of the fractional order parameter and temperature-dependent parameter are considered at the same time. The numerical results show that the values of temperature, displacement and stress increase with decreasing thermal conductivity, density and heat capacity at the interface. The fractional order parameter has a significant effect on temperature and stress, and a slight effect on displacement; the amplitudes of temperature, displacement, and stress decline with increasing temperature-dependent parameter. The decreases of thermal conductivity, density and heat capacity at the interface promote the heat transfer through the thickness direction of the plate, and the fractional-order theory and material temperature dependence have significant effects on the distributions of temperature, displacement, and stress are significant. © 2017, Editorial Department of Journal of Southeast University.
