Dynamic Mode III Crack Propagated with Constant Velocity at Interface Between Isotropic and Orthotropic Material

등방성체와 직교이방성체의 접합계면네 내재된 동적모드 III 균열의 등속전파

The dynamic problems of interface crack propagated with constant velocity along the interface of bimateraial composed of isotropic and orthotropicmaterial under antiplane loading condition are studied in this paper. The general dynamic stress fields and displacement fields of mode III are derived when interface crack between isotropic and orthotropic material is propagating with constant velocity. The general dynamic stress fields and displacement fields in isotropic material. Finally, the characteristics of interface crack propagation are studied with various properties of isotropic and orthotropic material and crack propagarion velocities.
