An improved life prediction model of corrosion fatigue for T-welded joint
Source abstract
Abstract
Abstract Fatigue and corrosion fatigue tests were conducted for T-welded joint specimens. The test results show that the corrosive environment greatly reduces the fatigue life of the specimens. The average reduction percentage under different stress ranges Δ σ were 47.7% ( Δ σ =172.5MPa ), 58% ( Δ σ =216MPa ) and 45.7% ( Δ σ =258MPa ) respectively. Based on Continuum Damage Mechanics (CDM), a corrosion fatigue life prediction model considering the coupling effects of corrosion environment and cyclic load was proposed. This prediction model can predict the corrosion fatigue life of present T-welded joint specimens and other specimens reported in previous researches, showing rationality and versatility.
