基于改进遗传算法的不锈钢混合硬化模型参数快速标定方法
基于常用结构不锈钢牌号奥氏体型S30408、S31608以及双相型S22053的循环加载试验结果,提出了基于经典混合硬化模型(Classical Combination of Isotropic and Kinetic Hardening model,CCIKH)的改进遗传算法(improved adaptive genetic algorithm,IAGA)和自适应子步积分方法联合使用的模型参数快速标定方法。结果表明,该方法相对于传统标定方法节约了大量人工工作和时间成本,且具有较好的精度和广谱性,更适用于不锈钢等不存在稳定滞回环的循环硬化不饱和及Non-Masing材料。提出的改进自适应遗传...
