Numerical Modeling of Coupled Thermo-elasticity with Relaxation Times in Rotating FGAPs Subjected to a Moving Heat Source

The time-stepping DRBEM modeling was proposed to study the 2D dynamic response of functionally graded anisotropic plate (FGAP) subjected to a moving heat source. The FGAP is assumed to be graded through the thickness. A Gaussian distribution of heat flux using a moving heat source with a conical shape is used for analyzing the temperature profiles. The main aim of this paper is to evaluate the difference between Green and Lindsay (G-L) and Lord and Shulman (L-S) theories of coupled thermo-elasticity in rotating FGAP subjected to a moving heat source. The accuracy of the proposed method was examined and confirmed by comparing the obtained results with those known previously.
