Stress intensity factors for an interface crack with impermeable surfaces between dissimilar electrostrictive materials

摘要: The asymptotic problem of a semi-infinite interface crack between dissimilar electrostrictive materials that are subjected to electric loading is numerically analyzed by using the finite element method. Numerical results displacement fields obtained on basis mathematical equivalence mode III and an electrostatic problem. shape size saturation zones explored as function ratio saturated displacements materials. In contrast with conventional wisdom, permittivities shown exert negligibly small influence fields. For various combinations material properties materials, stress intensity factors systemically calculated numerical effects electric, elastic, demonstrated.
