Abstract
Treated is an arbitrarily shaped anti-plane shear crack in a finite inhomogeneous piezoelectric domain under time-harmonic loading. Within a unified scheme different types of inhomogeneity are considered for which the material parameters may vary in arbitrary directions. The problem is solved by using a numerically efficient non-hypersingular traction BIEM. The fundamental solutions for the different inhomogeneity types are derived in closed form. Numerical results for the SIFs are discussed. They show the effect of the material inhomogeneity type and characteristics and the efficiency of the computational method.
