The thermo-electro-mechanical fracture problem of an infmite piezoelectric material containing a T-shaped crack is considered in this study. The problem is solved for an infmite piezoelectric material that is under a uniform heat flow, uniform mechanical loads in two directions and a uniform electric load far away from the crack region. The crack faces are supposed to be completely insulated. By using the Fourier transform, the thermal and electromechanical problems are reduced to systems of singular integral equations, respectively. The singular integral equations are solved numerically. Numerical calculations are carried out, and detailed results are presented to illustrate the influence of the thermo-electro-mechanical interaction on the stress and electric displacement intensity factors.
