摘要

•Factors affecting different methods for the determination of MSRC are analyzed.•Principles in the determination of MSRC are recommended.•The factor, α, is strongly dependent on the operative creep failure mechanism.•A relation exists between multiaxial factor, α, and damage tolerance parameter, λ.
