| 中文摘要: |
| 针对金属结构在腐蚀环境、力学载荷等因素耦合作用下的损伤问题，简要介绍了金属结构环境损伤的主要影响因素，对当前国内外金属结构累积损伤理论与模型进行了系统梳理，重点探讨了金属结构环境累积损伤研究未来发展方向。通过多层级“积木式”研究建立环境(腐蚀)损伤参量-力学性能退化关联模型，是解决金属结构环境-载荷耦合作用下损伤演变规律与机理、剩余强度/寿命评价与预测等关键问题的有效路径。 |
| 英文摘要: |
| 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. |
