摘要
通过对高分子聚合物细观形变过程的分析,提出形变区增殖的观点,由此导出较简洁的弹塑性本构方程,讨论了不同参数条件下应力~应变曲线形状的变化,与文献实验结果基本一致。
According to the analysis on micro-deformation process of polymers,the author proposes a new conception of deformed region' s multiplication, from which an explicit elastic-plastic constitutive equation can be deduced. The cliaracteristics of stress-strain curves in different parameter conditions are discussed. which are consistent with some experimental results of some references in principle.
