Fracture analysis of electromagnetic thermoelastic solids

This paper analyzes the problem of collinear permeable cracks in a magnetoelectroelastic solid subjected to uniform heat flow at infinity. The analysis is conducted according to the extended Stroh formalism. Concise expressions are given for the field intensity factors and the electric–magnetic field inside cracks. It is shown that all the field singularities are independent of the applied electric–magnetic loads, and the electric–magnetic field inside cracks is linearly variable with position along the crack line.
