An analytical method is introduced to solve the problem an orthotropic cylinder under thermal shock. The analytical expressions for the dynamic stresses and perturbation of magnetic field vector are obtained by means of a finite integral transform and Laplace transform. The response histories of dynamic stresses and perturbation of field vector are obtained, and the fopcusing effects of them are discussed.
