| 中文摘要: |
| 首先阐述了材料在循环载荷作用下的塑性累积特性，并重点介绍了仿真分析中常用的材料本构关系。然后从仿真和试验2个层面介绍了循环载荷作用下完整结构极限承载特性的研究工作，接着分析了裂纹损伤对循环载荷中结构承载特性的影响，阐明了裂纹在循环载荷作用下的变化规律。最后，总结讨论了循环载荷下损伤结构剩余强度评估方法及存在的问题，为研究人员提供一定参考。 |
| 英文摘要: |
| Firstly, the plastic accumulation characteristics of materials under cyclic loading were elucidatedand the commonly used material constitutive relations in simulation analysis were highlighted. Next, the research on the ultimate load-bearing characteristics of complete structures was presented from both simulation and experimental perspectives under cyclic loading. Then, the impact of crack damage on structural load-bearing characteristics under cyclic loading was analyzed and the variation patterns of cracks under such conditions were elucidated. Finally, the methods for evaluating the residual strength of damaged structures under cyclic loading and the existing issues were summarized and discussed, providing a reference for researchers. |
