本文提出了一种新的环形测试方法的实验研究。使用了优化环试样几何形状和环测试系统的新设计，这在早期的论文中有所描述。基于具有接触的三维弹塑性有限元建模，提出了一种确定全局力应力和全局位移应变的程序。研究了屈服强度、硬化率、杨氏模量和摩擦系数等不同参数对这些曲线的影响。对两种材料的有限元建模结果与环形试验结果进行了比较。一种是我们实验室已广泛研究的模型材料（铝硅，一种由硅颗粒增强的铝合金），第二种是核工业中使用的材料（锆合金）。
The experimental investigation of a new approach to the ring test is presented in this paper. A new design of an optimized ring specimen geometry and ring testing system was used, which was described in an earlier paper. Based on the three-dimensional elastoplastic finite element modeling with contact, a procedure for determining the stress from the global force and the strain from the global displacement has been proposed. The influences of different parameters, such as yield strength, hardening rate, Young's modulus, and friction coefficient on these curves has been examined. A comparison has been made between the finite element modeling results and the ring test results on two materials. One is a model material (aluminum-silicon, an aluminum alloy reinforced by silicon particles) that has been widely investigated in our laboratory and the second is a material (Zircaloy) used in the nuclear industry.
