    • Abstract
  • The Mises equivalent stress σ and the first stress invariant I1 were derived by considering the welding residual stress, loading stress and hydrogen induced stress; The influence of residual stress and hydrogen stress on yield behavior is analyzed theoretically, and the expression of apparent yield stress [σs] under unidirectional stress is derived; The influence of residual stress and hydrogen stress on fracture behavior is analyzed theoretically, and the expression of apparent fracture stress [Ib] under unidirectional stress state and the expression of eigenvalue Is1 under apparent yield state are derived.
