並列タイトル等Variation in Plastic Strain Range obf Metals During Fatigue Based on Logistic Analysis
一般注記The plastic strain range of stress-strain curve during fatigue process was measured for an annealed and rolled carbon steel S 45 C, SUS 304, aluminum, and copper alloys. The plastic strain range was evaluated from the movable dislocation density. It was found that the variation in movable dislocation density was expressed as a function of the number of stress cycles by the logistic curve based on the multiplication and annihilation processes of dislocations. It was concluded that the logistic curve is able to calculate the variation in plastic strain range and also the cumulative damage by taking into account the incubation period of cumulative in dislocation in the initial stage.
