摘要: The influence of Maxwell stresses on the generalized 2D fracture mechanics problem piezoelectric materials under combined mechanical and electric loads at infinity is studied. electrically semi-permeable crack boundary condition adopted in this paper. Based Stroh’s formalism, explicit closed-form solutions displacement inside crack, stress intensity factors are obtained. Numerical results also given to discuss effects when interior surrounding space filled with different dielectric medium. It found that factor increases rapidly increasing value applied load for case constant smaller than crack. always as or increase.
