NettetThe Johnson-Cook damage initiation criterion is a special case of the ductile damage criterion model for predicting the onset of damage due to nucleation, growth, and coalescence of voids in ductile metals. The model assumes that the equivalent plastic strain at the onset of damage is a function of stress triaxiality and strain rate. The …

NettetThis model is referred to as the “Johnson-Cook dynamic failure model.” ABAQUS/Explicit also offers a more general implementation of the Johnson-Cook failure model as part … Nettet2.2 Johnson-Cook model. The Johnson-Cook model (6) is a function of von mises tensile flow stress, in accordance with strain hardening, strain rate hardening, and thermal softening. Eq (1) represents a Johnson-Cook model, (1) where ε is the equivalent plastic strain, ὲ is the plastic strain rate and ὲo is a reference strain rate.

Nettet总结. ABAQUS中的损伤模型，都是损伤萌发的预测模型，由于课题研究是将残余应力描述为一种初始损伤，即损伤变量一开始就不为0，故采用ABAQUS损伤模型的意义不大。. 其次,参数的输入还依赖于实验得到的各种参数，不易获取。.
