Mechanical properties of low carbon steel in torsional and tensile loads

文章对低碳钢在拉伸扭转复合载荷作用下的力学性能进行研究,确定其极限应力状态。比较剪应力和拉应力比值变化时对其力学性能的影响。对单向拉伸破坏试验及扭转破坏实验的结果进行了分析,验证强度理论。总结规律,为工程实践中相应的问题提供参考。

For low carbon steel,tensile mechanical properties of composite torsion loads are studied to determine its ultimate stress state. Shear stress and tensile stress ratio changes are compared to know the effect on the mechanical properties. The experimental results of the uniaxial tensile and torsional damage test analyzed to verify the strength of the theory. The law is summed up to provide a reliable reference for engineering practice.
