在本文中，我们开发了一个模型，在一个一般框架内，已经开发来描述耗散系统的响应，为应变引起的聚合物固体的降解，由于断裂。通过纳入与这些过程相关的耗散率的适当形式，该理论可以推广到包括由于紫外线辐射、氧扩散等引起的降解。我们研究了这种降解聚合物梁的简单剪切和纯弯曲。(C) 2007 Elsevier Ltd.版权所有。
In this paper we develop a model, within a general framework that has been developed to describe the response of dissipative systems, for the strain induced degradation of polymeric solids, due to scission. The theory can be generalized to include degradation due to ultraviolet radiation, oxygen diffusion etc., by incorporating an appropriate form for the rate of dissipation associated with these processes. We study the simple shear and pure bending of such degrading polymer beams. (C) 2007 Elsevier Ltd. All rights reserved.
