摘 要: | 从聚合物的粘弹性特点出发,以其本构方程的有限形式的存在性,讨论、分析了聚合物的粘弹性系数的时变特性,论证了粘弹性系数随时间变化的必然性,给出了粘弹性系数的时变结果。该结果不仅适用于松弛问题,也适用于蠕变问题,尤其对既非松弛、又非蠕变的一般情形下本构方程的有限形式,更能体现其一般性,对于处理线性粘弹性问题具有一定的实用价值。

Analysis of Change with Time of Polymer''''s Viscoelastical Coefficent |

Abstract: | From polymer's viscoelastical characteristic,the paper demostrates and analysises some specific properties of the change with time of polymer's viscoelastical coeffcient,the necessity of viscoelastical coefficient change with time and some results.The result is valid not only for the relaxation problems but also for the creep problem,especial for the limited form constitutive equation of unrecaxation and uncreep problem in common.The limited form of constitute equation is more general and valuable in dealing with linear viscoelasticity.
