内容介绍:

In this talk, both the ratcheting including material ratcheting and structural ratcheting, and fatigue including high cycle fatigue (HCF) and low cycle fatigue (LCF) are discussed for structures subjected to cyclic loading condition. For the ratchet analysis of structures, both the bisection method and generalized method are presented using the Linear Matching Method (LMM) Direct Steady Cycle Analysis (DSCA) procedure. The LMM DSCA method and its software tool are further presented for the low cycle fatigue assessment of structures, with a comprehensive case study of a pressurized shell in the nuclear power plant, considering both the temperature dependent R-O model and the EPP model.  Finally the effects of creep on ratcheting and fatigue are discussed and the LMM extended DSCA is presented for the creep fatigue analysis of structures, with a detailed case study of Mental Matrix Composites (MMCs).
