| 摘 要： | 系统地回顾了含多处损伤MSD结构的损伤连通准则,指出采用Dugdale的片状塑性区尺寸的Swift韧带屈服准则对一般工程材料最为合适.对具有潜在危险性的典型的广泛MSD结构作了剩余强度分析,分析结果表明:广泛MSD大大地降低了结构的剩余强度.

| Abstract: | This paper reviews damage linkup coriterion for multiple site damage(MSD)structure in a systematic way and points out Swift yield criterion of Dugdule lamellar size at plastic zone is most suitable for general engineering materials.It analyses residual strength for typical widespread MSD structure with potential danger.The analysis result proves wide spread MSD residual strength of structure greatly. |
