PHYSICAL CHARACTERISTICS AND MECHANICAL BEHAVIOUR AT CRACK TIP IN DUCTILE FRACTURE
-
摘要:本文综述了金属材料发生韧性断裂的裂尖钝化,孔洞成核和长大,孔洞-孔洞或孔洞-裂尖汇合导致裂纹扩展的物理特征,和描述这些特征的本构理论及物理模型。Abstract:The ductile fracture characterstics which include crack-tip blunting, and void initiation, growth and its coalescence with voids or blunted crack-tip and the constitutive theories and fracture models for the corresponding physical behaviour are reviewed in this paper.
