摘要
通过对W alker模型中各参数物理意义的分析,初步建立了工程用粘塑性模型的参数拟合方法,并以AISI 316L材料为例,初步验证了该方法的可行性。
With analysis of physical meaning of Walker's unified viscoplastic constitutive model parameters, an parameter fitting method for viscoplasfic constitutive models was established. The method was validated using material AISI 316L as an example.
