Transient magneto-thermo-viscoelastic stresses in a nonhomogeneous anisotropic solid with and without a moving heat source under rotation are studied. The system of fundamental equations is solved by means of the dual reciprocity boundary element method (DRBEM). In the case of plane deformation, a numerical scheme for the implementation of the method is presented, and the numerical computations are carried out for the temperature, displacement components, and thermal stress components. The validity of the DRBEM is examined by considering a magneto-thermo-viscoelastic solid that occupies a rectangular region, and good agreement with the existent results is obtained. The results indicate that the effects of a moving heat source and rotation are very pronounced.
