Sidiroff的能量等价原理
Web【摘要】：ABAQUS混凝土损伤塑性模型可以有效用于混凝土结构性能研究,但模型中真实的损伤因子往往由于试验条件的限制难以被获取,为此提出一种损伤因子的计算方法。基于混凝土结构设计规范提供的混凝土本构关系,运用Sidiroff能量等价原理对损伤因子进行推导,采用数值模拟与试验研究相结合的 ... WebSep 10, 2024 · 基于 摩尔 ——库仑 模型 软土地基力学参数的敏感性分析. 摩尔—库仑模型是岩土工程有限元计算中的常用模型,模型参数需通过剪切试验或三轴排水试验得出。. 由于软土地基材料的特殊性,试验不易得到部分参数的准确值。. 采用ABAQUS建模进行了软土地基算例 ...
