摘要
本文根据形变功理论及有限元结果证明了Ｄｏｗｌｉｎｇ△Ｊ实用与循环Ｊ积分线积分△ＪＰａｔｈ及△Ｊ形变功三者一致．
The consistency of the △Jpayh defined by a path independent line integral and op-erational△J defined by Dowling and the △ J evaluated from the work of defourmation is proved. On the basis of this conclusion,the △J of non-standard specimens or engineering structure may be calculated.
