| Abstract: | The method of determination of the pre-fracture zone length and the crack opening displacement for a plain strain problem of electrically permeable crack located in a thin interlayer between two identical piezoelectric materials is suggested. This method takes into account certain stress distribution appearing at the crack continuation. This distribution is related to interlayer yielding or damage and it can be found experimentally or theoretically. |
