摘要
根据J积分与路径无关性原理,提出了起裂点的J Δa0关系式:J=(1/1+n)Kε1+nf×2Δa。通过对16Mn钢的J积分测试,认为该式计算的Δa0与实测钝化带宽度符合得比较满意。
On the base of path-independence of J-integral, the relationship of J-integral and Δa_0 was obtained. The result was as follows: J=11+nKε^(1+n)_f×2Δa. By J-integral measuring of 16Mn, Δa_0 values estimated by this relation satisfactorily conform to the experimental results.
