沥青混凝土永久变形的鉴定与模拟

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。

Asphalt Concrete Permanent Deformation Appraisal and Simulation

This article has studied under the redundant load function the asphalt concrete accumulation permanent deformation,and proposes one kind of new multi-dimensional misalignment,the super-elasticity,the non-related plastic model.Using indicated that the adjustment algorithm solves the description model the equality.The model result and the practical experience data compare,this is very advantageous.One very obvious result,the model parameter which obtains from one kind of stress level's experiment may extrapol...
