| Abstract: |
| Aiming at the damage of metal structure under the coupling action of corrosion environment, mechanical load and other factors, the main influencing factors of damage of metal structure under environment were briefly introduced. The current theories and models of cumulative damage of metal structure at home and abroad were systematically sorted out, and the future development direction of cumulative damage research of metal structure under environment was mainly discussed. It is an effective way to solve the key problems of damage evolution rule and mechanism, residual strength / life evaluation and prediction under the coupling effect of environment and load of metal structure, by establishing the correlation model of environmental (corrosion) damage parameter-mechanical property degradation by multi-level “building block” study. |
