摘要
针对混凝土结构设计规范中的混凝土本构模型经过换算需与ABAQUS损伤塑性模型对应统一的问题,引入了在ABAQUS内对压缩和拉伸通用的损伤因子计算方法,对混凝土损伤塑性本构模型的参数计算转换方法进行了研究与试验,确定了利用塑性应变值来判断各种强度等级混凝土损伤塑性参数的可用性。在ABAQUS中用简支梁模仿真数值模拟试验验证了参数的正确性与计算转换方法的可靠性,并说明了ABAQUS损伤塑性模型的不足之处。
The concrete constitutive model in concrete structure design code should be unified with the damage plastic model of ABAQUS.It introduced a general damage factor calculation method for compression and tension in ABAQUS for research and experiment on parameter calculation and transformation method of concrete damage plastic constitutive model.The plastic strain value is determined to judge the availability of damage plasticity parameters of various concrete.In the ABAQUS,the numerical simulation test of the simply supported beam model is used to verify the correctness of the parameters and the reliability of the calculation and transformation method,and the deficiencies of the ABAQUS damage plastic model are also illustrated.
