摘要
利用有限元分析软件,对采用不同本构关系和不同荷载等级的混凝土小型砌块的非线性力学性能作了试验模拟分析,包括计算模型的简化、单元和破坏准则的选取、网格划分以及求解等。并对数值模拟的结果进行了具体的分析,对混凝土小型砌块的非线性和线弹性的模拟结果也进行了比对,为混凝土结构非线性分析和混凝土小型砌块的力学性能研究以及优化提供参考依据。
Based on finite element analysis software, by using different strain and stress relations and different load, the non-linear mechanical performance of small concrete block has been analysis,including：model simplification;unit type and stress-strain relations selection;grid division and solution.Simulation result has been concluded too.Finally analogue result of the concrete block non-linearity and the line elastic has been advanced;it will offcr more useful help for mechanics property and optimized design of small concrete block and other concrete structure.
