| Abstract: | In this paper, it is analyzed the plastic stress field of the plane-strain crack-tip of mode I which intersects perpendicularly to the interface of two phase of media (isotropic and orthotropic materials) and is in the isotropic material. both of the isotropic and orthotropic materials are regarded as perfect-plastic and each of them satisfies the Mises criterion Hill criteri criterion, the plastic stress field at the crack-tip is gained. |

| Keywords: | Isotropic orthotropic interface stress characteristic of crack-tip |
