Abstract

Abstract

The accelerated corrosion test of Q690 high-strength steel was carried out for 0-100 d in the periodic wetting and humid hot environment. The degradation law of mechanical properties of steel was studied by uniaxial tensile test. The stress-strain degradation constitutive model of corroded specimen was established by using secondary plastic flow model, and the relationships between parameters s₁ and corrosion time, s₂ and corrosion time were obtained. The results were compared with the experimental results. It could be concluded that the yield strength, tensile strength and elongation after fracture and other mechanical properties of Q690 high-strength steel decreased in varying degrees due to the increasing corrosion. The elastic modulus of Q690 high-strength steel had no obvious change in the early stage of corrosion, but it decreased by 10.2% in the later stage of corrosion. The secondary plastic flow model could better reflect the constitutive relationship of corroded steel. The finite element simulation of corrosion pit exploitation of steel could better reflect the degradation of bearing capacity of corroded high-strength steel, which was in good agreement with the test results.
