文章研究了在重复荷载作用下沥青混凝土的累积永久变形,并提出一种新型多维非线性、超弹性、非相关塑性模型。利用预示校正算法来求解描述模型的等式,模型结果与实际经验数据相比较,这是非常有利的。一种很明显的结果,从一种应力水平下的试验中获得的模型参数可以精确推测出另外一种应力水平下的试验结果。 In this paper, the cumulative permanent deformation of asphalt concrete under repeated loading is studied and a new multi-dimensional nonlinear, hyperelastic and non-related plastic model is proposed. Using the predictive correction algorithm to solve the equation describing the model, it is very beneficial to compare the model results with the actual empirical data. One obvious result is that the model parameters obtained from one stress level test accurately predict the test results at a different stress level.
