Abstract. The fracture of piezoelectric grab is considered on the base of solution for the problem of linear slit in the plane boundary of half-space filled with piezoelectric material. A combined criterion of grab fracture is proposed. Application of aggregate D-module is shown to be appropriate for the limit curves construction.
Keywords: piezoelectric grab, energy criterion, piezomodule.
