Mark J1C at theintersection of the two lines.It is necessary to use a new standard specimen to do J-integral test. The dimension of standard specimen is 10 mnx20 nsnxiOO mm .The results from this specimen are satisfied with the condition of validness of J-integral as well as the condition of plane-strain. The reason is explained.
