摘要
针对疲劳过程模拟中逐步有限元分析耗时太长、在实际应用中不能被接受的现状,基于具有物理机理的混凝土疲劳的本构模型研究了疲劳计算中的加速计算方法——基于预测—外推的跳跃算法。通过二次开发程序接口,使得所研究的加速算法能够与有限元分析软件ABAQUS密切结合,从而使得应用疲劳本构模型直接进行混凝土结构疲劳全过程分析成为可能。
Considering it is too time consuming to perform FEA simulation when cooperating the fatigue constitutive model with actual structures,a type of acceleration computing methods is developed in which the cycle jump is based on the process of prediction and extrapolation.With combing the method with the fatigue constitutive model developed earlier by the author,the accelerating computing process is performed in FEA software ABAQUS where secondary development with the software interface is required.The simulated results show the accelerating computing results are well agreed with step by step simulation and the experimental results.
