Based on machine learning 316 stainless steel low-cycle fatigue life prediction method

AbstractThe low cycle fatigue life of 316 stainless steel is a significant basis for safety assessment. Usually, many factors affect the low-cycle fatigue life of stainless steel, and the relationship between the influencing factors and fatigue life is complicated and nonlinear. Therefore, it is hard to predict fatigue life by the traditional empirical formula. Based on this, a machine learning algorithm is proposed. In this paper, based on the existing large amount of experimental data, machine learning methods are used to predict the low circumferential fatigue life of 316 stainless steel. The results show that the prediction accuracy of nu-SVR and ELM models is high and can meet engineering needs.
