%X In this paper, the ductile fracture characters of polycarbonate plate are studied. A modified hardening Dugdale strip yield model is proposed. The stress filed around ductile crack tip is determined by hybrid experimental-numerical analysis method. Experimcntal results show good agreements with theoretical isochromatics and lengths of strip yield zones. So that the developed modified hardening Dugdale strip yield model is reasonable.
