分数Maxwell模型在高密度聚乙烯蠕变中的应用
Application of fractional Maxwell model to creep of high-density polyethylene
摘要
Abstract
The creep curves of high-density polyethylene at different stress levels and aging time were fitted using generalized fractional Maxwell model. Genetic algorithm and conjugated gradient method were employed to optimize the model parameters. When the time was scaled by the relaxation time, the creep curves at the same stress levels and different aging time can superpose very well. It means that the time-aging time superposition is naturally satisfied.关键词
