It is found that with the variation in stress triaxiality from the big to the small,the fracture mechanism of materials is in the sequence of cleavage,traction fracture,shear fracture with cavity,plastic shear fracture and seam,and also that when the shear fracture with cavity takes .
通过研究几种合金钢在常规破坏试验和复合型断裂试验过程中的断裂现象,分析不同应力状态下的断裂试验结果,发现随应力三维度由大到小变化,材料的断裂形式依次为组织断裂、孔洞正断、孔洞剪断、塑性剪断及焊合。
