【摘要】 <正> 一、循环扭转下材料的特性 35钢材料一次扭转断裂和反复多次断裂,两者的本构关系不同.实验在岛津DCS25t试验机上进行,频率为3—5cyc/min.试样机械加工成直径12mm、标距长150mm的圆柱. 35钢为热轧一般质量的更多还原

【Abstract】 Studies were made of the material performance of steel 35 under low cycle torsion as well as the relationship of the low cycle torsional fatigue life together with the torsional strain amplitude and fatigue energy under torsion strain. The feature of the fatigue failure of the steel under low cycle torsion was also discussed.更多还原
