本文对45号钢在静载荷下与在循环加载下的本构关系进行了探讨，并给出了低周与高周应变循环的疲劳寿命表达式。
The 45 steel natural relation of dead load with cyclic load and low frequency and high frequency strain cycling fatigue life are studied.
为了解决具有异形内轮廓的冲压件翻边工序中易产生裂纹等缺陷，分析了异形内轮廓翻边成形时周向应变分散效应。
In order to solve the lack of flaw when flanging the part with freeform internal profile, the circumferential strain dispersion effect has been analyzed in flanging the profile.
结果表明，扭转预应变降低低周疲劳寿命，循环应力随扭转预应变的增大而增大。
The results show that low cycle fatigue life is reduced and cyclic stress is raised by torsional prestrain raising.
