摘要
根据金属基复合材料在高应变率下的超塑性变形机理 ,讨论了已有的超塑性本构描述的优缺点 ,提出了获得精确描述高应变率下材料响应本质特征本构方程的几点看法 ,为超塑性成形的数值模拟提供理论基础。
The studies taken by researches on the superplastic deformation behaviors of ceramic whiskers or particulates reinforced MMCs under high strain rate were reviewed, and some discussions were made on the features of constitutive models supposed before. Some ideas were proposed on the precise constitutive description of superplastic materials' dynamic response under high strain rate.
