中文摘要：

本文用分子动力学方法对聚碳酸酯非晶结构在运动压缩下的变形进行计算机模拟，通过分析聚碳酸酯在单轴压力下的网络结构，以及分子链二面角分布随压力的变化，获得聚碳酸酯对运动变形的分子响应。研究发现聚合物材料在塑性流引发下膨胀，证明了压力感应活性的出现。

英文摘要：

The plastic deformation of amorphous glassy bis-phenol-A-polycarbonate （BPA-PC）within the stress strain response of the system was studied based on force field method and molecular dynamics simulations. The molecular response of a glassy polymer to active deformation was investigated via analysis of net structures and dihedral angel distribution of BPA-PC. The results indicated that the glassy polymer were expand by the stress induct and clearly demonstrate the appearance of stress-induced mobility.
