- Abstract
This paper proposed a simple life prediction model for assessing fatigue lives of metallic materials subjected to multiaxial low-cycle fatigue (LCF) loading. This proposed model consists of the maximum shear strain range, the normal strain range and the maximum normal stress on the maximum shear strain range plane. Additional cyclic hardening developed during non-proportional loading is included in the normal stress and strain terms. A computer-based procedure for multiaxial fatigue life prediction incorporating critical plane damage parameters is presented as well. The accuracy and reliability of the proposed model are systematically checked by using about 300 test data through testing nine kinds of material under both zero and non-zero mean stress multiaxial loading paths.
