✦ Synopsis

In this paper, as is studied are the electro-elustic solutions for a piezoelectric barspace subjected to a line force, a line charge and a line dislocation, i. e., Green's functions on the basis of Stroh formalism and the concept of analytical continuation, explicit expressions for Green's functions arc derived. As a direct application of the results obtained, an infinite piezoelectric solid containing a semi-infinite crack is examined. Attention iffocused on the stress and electric displacement fields of a crack tip. The stress and electric displacement intensity factors are given explicitly.

This paper presents analytical Green's function solutions for an isotropic elastic half-space subject to antiplane shear deformation. The boundary of the half-space is modeled as a material surface, for which the Gurtin-Murdoch theory for surface elasticity is employed. By using Fourier cosine trans
