粘弹性泊松比的各种表述方法

The Formulations of Viscoelastic Poisson's Ratio

本文讨论线性粘弹泊松比的四种表述法:微分算子法、遗传积分法、复数表示法和经验表示法的实用价值和问题。为固体推进剂力学性态的描述提供了方便。

This paper rewiews four formulations of viscoelastic Poisson's ratio,which are the formulation by differential operators ,the formulation by hereditary integral and by complex and empirical methods. Also discused are the domain ralidty and problems of these methods, which provide convenient description of mechanical behaviors of solid rocket propellants.
