摘要
根据聚合物时间相依的粘弹性机理 ,对 PMMA(聚甲基丙烯酸甲酯 )试件进行了单轴拉伸实验 ,着重研究了高聚物粘弹性变形的非线性及应力水平相关性 .在此基础上 ,拟合实验数据 ,得到了各个蠕变材料参数 。
According to the time dependent mechanism of viscoelasticity in polymer, three groups of single dimension stretching experiment were conducted on PMMA in this paper, the non linear and stress dependent quality of viscoelastic deformation in polymer were researched emphatically. On the basis, we fitted the experimental data and then attained the material parameters, compared and analyzed some existed creep theories of single dimension.
