The long-term response of polymers and polymer matrix composites to combined static and cyclic loads will be studied. The particular objectives of the project are to determine the response to cyclic creep, or vibrocreep, of a designated group of polymers and polymer composites; to determine the effects of microstructural processes; to develop consistent constitutive models to characterize cyclic and temperature dependent creep properties of polymers; and to validate accelerated experimental techniques in terms of their predictive capabilities for vibrocreep and the effect of damping. The study is a joint effort between the Montana State University and South Dakota School of Mines.

将研究聚合物和聚合物基复合材料在静载荷和循环载荷联合作用下的长期响应。该项目的具体目标是确定指定的一组聚合物和聚合物复合材料对循环蠕变或振动蠕变的反应；确定微结构过程的影响；开发一致的本构模型，以表征聚合物的循环蠕变和依赖于温度的蠕变特性；并验证加速实验技术对振动蠕变和阻尼效应的预测能力。这项研究是蒙大拿州立大学和南达科他州矿业学院联合开展的。
