The Progress of Engineering Evaluation Method of J-integral in Structure Containing Defect
Gang Chen · Pressure vessel Technology · 2006
As the fracture assessment method based on COD theory is replaced by the method based on J-integral theory,it is greatly required simple and convenient,reliable evaluation method of J-integral.In this paper,some engineering evaluation methods of J-integral are described,some problems in these methods are raised,and the developing trend of these methods is discussed.This paper provides assistant for advanced development of fracture assessment method of structure containing defects.
