Determination of Intensity Factors for Interfacial Cracks in TIP Materials

Abstract:

An explicit extrapolating formula for a general case of the interfacial crack plane lying with an angle to the poling axis in transversely isotropic piezoelectric (TIP) materials is derived, which is very feasible to determine the intensity factors for numerical methods such as FEM or BEM. Additionally, a more concise extrapolating formula for the typical state of the interfacial crack plane lying perpendicular to the poling axis is also presented in this paper.
