چکیده مقاله
The behavior of thermoelastic waves at the interface of layered medium and distributions of these waves through the domain are examined by applying the gdq method to obtain the field variables directly within the spatial domain and newman method to temporal domains The analysis is performed in a one dimensional domain with two different layers to provide a means to follow the behavior of the reflected thermoelastic waves at the interface It appears that the distributions of thermoelastic waves in an isotropic slab with one layer are significantly different from those in multilayered slabs For instance, the negative or positive displacement waves, several stresses with positive or negative signs and temperature distributions produced in the multilayered domains, are quite different from those in a single layer This method may be generalized to simulate the propagation of thermoelastic waves in various multilayered regions and analyze the behavior of the layered composite structures under the mechanical or thermal impact loads
