摘要
分析了低循环疲劳循环滞回能的循环相关性特点，给出了循环滞回能瞬态响应的数学模型．与已有的模型比较，本文给出的模型能准确地描述循环滞回能的循环相关事实，并且与试验结果符合较好．另外。
he cyclic correlativity of the hysteresis energy in low cyclic fatigue is analysed in thispaper.The transient response mathematical model of the hysteresis energy is given. Themodel can accurately express the facts of the hysteresis energy cyclic correlation as compared with previousmodel, and conform satisfactorily to the experimental results. In addition, based on this model, the calculating equation of the total absorbed energy due to failure is obtained.
