本文根据Nadai解，讨论了一种通过实心轴扭转试验确定材料真实（柯西）剪切应力-应变曲线的方法。该方法适用于加载、卸载和循环加载。它也适用于大剪应变范围内实心轴的固端扭转。对于大应变范围内的管状试件自由端扭转问题，本文还提出了一种改进的计算方法。
This paper discusses a method, based on Nadai`s solution, which can be used to determine the true (Cauchy) shear stress-strain curve of a material by means of torsion test of a solid shaft. The method is shown to be applicable to loading, unloading and cyclic loading. It is also applicable to fixed-end torsion of a solid shaft in the large shear strain range. A modified method has also been derived for the case of free-end torsion of a tubular specimen in the large strain range.
