Influence of Circular Void on a Crack in a Piezoelectric Material
압저재료에서 원공결함이 균열에 미치는 영향
Abstract
In this paper, the influence of circular void on a crack in piezoelectric materials under mechanical and electric loads is investigated by using finite element method code, ANSYS. Both ceramics and piezoelectric materials are compared with stress intensity factor and crack extension force at crack tip on arbitrary located circular void under Mode I loads. It was found that piezoelectric materials's crack extension force is larger than ceramics.
