Comparison of Different Fracture Mechanics Test Procedures Which Give Critical Values in the Description of Fracture Behavior

摘要

The methods used in elastoplastic fracture mechanics for the determination on reduced scale models of fracture resistances comparable to those given by the ASTM E 399 concept are reviewed. The experimental values are compared. Included are the equivalent energy method the J-integral concept and the crack opening displacement concept. It is concluded that these methods provide sufficiently exact determination of critical fracture resistance from reduced scale specimen tests.
