摘要
以Norton公式为例,提出了一种利用平头压痕试验确定材料蠕变参数的一种新方法。
A new possible method to determine the creep parameters for a simple Norton law material from the flat cylindrical indentation creep testing by the finite element method is presented. The analysis was based on the relationship between the steady indentation depth rate and the assumed creep parameters at constant load. The results show that the creep parameters can be determined by two different sizes of the indenter. At last an example was given basing this new method.
