| Abstract: |
| A numerical analysis method is proposed to calculate accumulative damages of corrosion and wear of chain link in service period.Both the corrosion of chain annulus in seawater environment and the wear of contact surface between adjacent links can be considered by using non-linear finite element analysis.For determining mechanical properties of the chain steel used in the finite element analysis,mechanical tests with the low-carbon and low-alloy steel 22MnCrNiMo are carried out to obtain its material hardness,seawater erosion and corrosion wear resistance.Numerical results and experimental data are compared to verify the feasibility and accuracy of the proposed method. |
