    • Abstract
  • An analysis is given on the whole J-R curve patterns which were obtained under stable crack growth in a fully plastic region. The formulas for dJ/da with load factor L of test piece, CTOA and instantaneous factor of rotation r* are presented. The effects of geometric size of test piece on J-R curve under different degree of constraint are discussed
