【Abstract】 By using stress strength factors considering crack surface turning instead of those nonconsidering crack surface twist,on the basis of maximum strain criterion within a small range of yield strength,the critical crack length of the Ⅰ Ⅲ comopsite crack is estimated.The residual life of Ⅰ Ⅲ composite crack is then estimated.The experiment shows that this estimation method can be used for engineering.更多还原
