Green functions of piezoelectric material with an elliptic hole or inclusion

In this paper, the Green functions of infinite two-dimensional piezoelectric material containing an elliptic hole or an elliptic piezoelectric inclusion are obtained with the extended Stroh formalism. The results can be used to investigate the mechanical-electric coupling behaviours of infinite piezoelectric material with hole or inclusion acted by a set of generalized concentrated forces, and more importantly as kernels of boundary integral equations in BEM analyses for finite size piezoelectric materials with general forces and boundary conditions. © 1997 Elsevier Science Ltd
