摘要
考虑到静水应力分量可以抑制材料延性破坏的重要特性,从能量观点提出了冷锻材料破裂准则,并作了实验验证,可用于金属冷锻成形的破裂预测,指导生产实践。
By considering both the conservation of energy of plastic deformation an and the effect of hydrostatic pressure on the ductile fracture a criterion for ductile fracture of material under cold forging is proposed and it is used to predict ductile fracture of material in cold forging.
