Abstract

Piezo-ceramics are brittle; they can fail untimely due to the propagation of flaws or defects produced during their manufacturing process. ln this paper, we propose a numerical estimate of a J -integral generalized to electro-mechanical processus, wich will prove useful in designing a propagation criterion. To that end, we use the finite-element method to solve the piezo-electric problem, providing thus displacements and coordinates of elements that constitute the chosen integration path. Then the computation of J is achieved by using the energydomain- integral methodfor piezo-ceramics such as PZT-4H and PZT-SH.
