The Role of Volume Changes in the Nonlinear, Time-Dependent Mechanical Response of Amorphous Structural Polymers

9504144克瑙斯这个项目将研究结构聚合物的非线性随时间变化的本构行为。特别强调的是阐明膨胀在时间相关力学行为中的作用，并为时间相关聚合物断裂提供一个框架。这项研究集中在随时间变化的材料行为中发生的小体积变化。初步的扭转试验表明，在这种聚合物的试验中会发生体积变化。***

9504144 Knauss This project will study the nonlinear time-dependent constitutive behavior of structural polymers. It is a particular emphasis to elucidate the role of dilatation on the time dependent mechanical behavior and to provide a framework for time dependent polymer fracture. The study centers on the small volume changes that occur in the time dependent material behavior. Preliminary torsion tests have showl that the volume changes occur in such tests of polymers. ***
