Abstract
A boundary element method (BEM) for the analysis of two-dimensional, t ime independent problems of linear electro-elasticity is presented. Em phasis is given to the derivation of representation formulas and funda mental Solutions as well as to the construction of an efficient numeri cal algorithm. The method is particularly suitable for studying the be havior of active materials such as electrostrictive, ferroelectric and piezoelectric ceramics. Two numerical examples with direct impact on the structural safety and reliability of piezoceramics are provided to demonstrate the virtues of the new BEM. (C) 1997 Elsevier Science Ltd .
