摘要
基于弹性损伤理论,并与有限元法相结合,形成损伤力学—有限元法,并自编了相应的计算程序,对沥青混凝土梁试件疲劳全过程进行了数值模拟计算与分析,理论计算结果与实际应用规律可以较好地吻合,说明本文提出的方法可用于描述水泥混凝土材料的疲劳特性。
Based on the elastic damage theory and combining with finite element method,the author establishes the damage mechanics-finite element method,and programs corresponding calculation program,gets numerical simulation calculation and analysis on the whole process of the asphalt concrete beam specimen figure.The theory calculation accords with practical application law better,which proves that the provided method can be used as describing the figure characteristics of the cement concrete material.
