Abstract:The reference stress method (RSM) is a classical method to estimate C*-integral of creep crack. An extended reference stress method (ERSM) is given for the central cracked plate (CCP) under biaxial loading in this paper. The applicability and verification for the proposed ERSM is given. The study finds that the solutions with the proposed ERSM agree better than those of RSM under biaxial loading condition. A theoretical form to predict the relationship of C *-integral between biaxial loading and uniaxial loading is discussed. Relation between C*-integral and creep time under biaxial loading is validated and discussed.
