The Application and Extension of Sachs Method

摘要: 本文提出测量平面应力状态厚壁圆筒残余应力时Sachs公式的简化,特别提出了测量和计算具有轴向残余应力有限长厚壁圆筒残余应力的方法.这些结果可用于研究火炮自紧身管内的残余应力.

Abstract: In this paper,we present the simplification of Sachs formulas for the measurement and calculation of the residual stresses of the cylinder only with the plane stresses. Furthermore, we present the method for the measurement and calculation of the residual stresses of the cylinder not only with the finite length but with the longitudinal stress. These can be applied to the investigation on the residual stresses of the autofretted gun tube.
