Problem 1: Part 8: Consistency condition - 2 edit
The yield stress is given by the Johnson-Cook model
where is the initial yield stress, are constants, is a reference temperature, and is the melt temperature. Derive expressions for , and for the von Mises yield condition with the Johnson-Cook flow stress model.
The yield function is
