A Corten-Dolan model considering material strength degradation …
Corten and Dolan [] put forward two hypotheses by analyzing a large number of test data: (1) In the loading process, the number of damage cores depends on the high level of stress, and once generated, it will continue to accumulate until failure, so p i = p max. (2) Suppose, a = a i = a max and (r i /r max) 1/a = (σ i /σ max) d.According to …
