Abstract
First, based on the basic equations of piezoelectricity, the boundary integral formulation is derived by utilizing the reciprocal-work theor em. Second, for the plane problem of piezoelectric media, one general solution in terms of 'harmonic functions' is derived and the fundament al solutions are therefore obtained. Numerical calculations by boundar y element method (BEM) are performed to give the stress concentration coefficient of an infinite piezoelectric plane with a circular hole as well as the stress and electric intensity factors of a central crack locating on an infinite plate. Results are found to agree well with th e exact solutions. (C) 1998 Elsevier Science S.A.
