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。
3) ductile fracture
塑性断裂
1.
Experimental results show that along with the increment of samples thickness,SP impact energy increases,fracture surface displays typical ductile fracture,and the punched part is full of half-sphereicl little bulge.
采用临界塑性断裂应变作为裂纹起裂判据,单位面积的能量耗散率作为裂纹扩展和失效判据的断裂模型,用有限元方法对SP压杆实验进行模拟,得到与实验结果比较相符的模拟结果。

5%的F+M双相钢;动态拉伸过程中,裂纹尖端的塑性区会萌生新的微裂纹,塑性区内的铁素体晶粒内部会产生"波状"滑移带;当裂纹扩展到马氏体岛时会改变方向绕过马氏体,扩展到铁素体晶粒时,以微孔相连的塑性方式使铁素体开裂;最终断裂以塑性断裂的形式发生,断口形貌为韧窝状。
