A larger error often occurs in measured results by multi-specimen J-R curve method because of the difficulty in determining the blunting line equation. On the basis of considering the effect of loading rate on plastic-flow stress, a new blunting line equation in dynamic loading has been obtained: J=2NK0.5(subscript εFΔa.

针对多试样J-R阻力曲线法因钝化线的不易确定性常造成测试结果J误差较大的情况，考虑了加载速率对塑性流变应力的影响，给出了一新的动载条件下的钝化线方程：J=2NK0.5
