摘要: In this work, the heat conduction with finite wave speed of multi-layered domain made functionally graded materials (FGMs) subjected to generation is simulated. For purpose, divided into a set mathematical layers, number which can be equal or greater than those physical layers. Then, in each layer, non-Fourier transfer equations are employed. Since, governing have variable coefficients due FGM properties, as an efficient and accurate method differential quadrature (DQM) adopted discretize both spatial temporal domains layer. This results superior accuracy fewer degrees freedom conventional element (FEM). To verify advantages through some comparison studies, solution also obtained. After demonstrating convergence method, effects for two different boundary conditions on temperature distribution flux studied.
