The kinematically admissible velocity field and strain rate field for extension forging of rounds have been established.
建立了圆坯拔长锻造的运动许可速度场与应变速率场。
2
The effect of forging rate on strain is not obvious.
锻造速率对坯料应变的影响不显著。
3
Besides, in the position of larger value stress the local strain is smaller that coincide with the law of stress and strain change during the common forging process.
