研究了稳态加载条件下聚合物纤维的冷拉伸速率和温度依赖性材料性能。刚塑性流动理论法，它结合了材料的应变率敏感性和热软化性能。变形引起的加热的不稳定效应的影响进行了研究，其中的热机械响应被假定为发生在绝热条件下。通过各种参数的研究材料的应变率敏感性和不稳定的影响变形诱导加热的稳定效果之间的相互作用进行检查。
Cold drawing of polymeric fibres exhibiting rate and temperature dependent material properties is studied for steady-state loading conditions. A rigid-plastic flow theory law which incorporates both material strain-rate sensitivity and thermal softening properties is employed. The destabilizing effect of deformation-induced heating is investigated where the thermomechanical response is assumed to take place under adiabatic conditions. The interplay between the stabilizing effect of material strain-rate sensitivity and destabilizing influence of deformation-induced heating is examined through various parametric studies.
