When an isotropic perfectly conducting solid cylinder is subjected suddenly to a uniform temperature rise in an axial magnetic field, a magnetothermoelastic stress wave occurs on the surface the instant the thermal impact is applied. The stress wave on the surface proceeds radially toward the center of the cylinder. The wave may accumulate at the center and give rise to very large stress magnitudes, even though the initial thermal stress is relatively small. This phenomenon is called the stress-focusing effect. This paper analyzes the effects of these waves precisely using the ray series. The results give clear indications of the mechanism of magnetothermoelastic stress-focusing effect in a perfectly conducting solid cylinder in an axial magnetic field.
