摘要	The fracture morphology of the fragments caused by the layer split of the ultra-high strength steel target under penetrating was investigated by scanning electron microscopy. The results show that the fracture morphologies of both front and back fragments are divided into different areas which correspond to the different stages of the initiation and propagation of crack. For back fragment, there are wave-like dimples in its central area, indicating that the tensile stress is responsible for the initiation of the crack. Outside the central area is the flat region consisting of parabola-shape dimples indicating the propagation of the crack resulted from the interaction of opening and sheraing. The dimples in the Ranks of both front and back fragments are all equal-axis ones suggesting that the fragments are finally broken by tensile stress. The process of the layer split is ductile rupture. The effect of layer split on protective ability of target was briefly discussed.
