垂直き裂を有する圧電セラミックス半無限体の電気熱弾性相互干渉

This study investigates the electromechanical fracture behavior of a normal crack in a semi-infinite piezoelectric material subjected to a uniform heat flow far away from the crack region. The crack faces are supposed to be insulated thermally and electrically. By using the Fourier transform, the thermal and electromechanical problems are reduced to singular integral equations, respectively, which are solved numerically. Both the cases of as internal crack and an edge crack are studied. Numerical calculations are carried out, and detailed results are presented to illustrate the influence of the crack location on the temperature distribution and the stress intensity factors
