钢轨的材料参数直接影响着钢轨的屈服现象和应力状态。文章详细地研究了轨头内弹塑性接触应力场与钢轨材料参数(弹性模量、泊松比、应变硬化模量、屈服极限)的相互关系。
The material parameters of the rail directly affect the yield phenomenon and the stress state of the rail. In this paper, the relationship between elastic-plastic contact stress field and rail material parameters (elastic modulus, Poisson’s ratio, strain hardening modulus, yield limit) is studied in detail.
