摘要
应用ANSYS中的参数语言建立混凝土随机骨料结构模型,并对该模型在单轴受拉、单轴受压及双轴拉压组合下的加载过程进行较详细的数值模拟,分析加载过程中变形场应力应变变化情况,进一步揭示了混凝土的损伤机理并证明了模型用于模拟混凝土试验的合理性。
A concrete model with random aggregate has been built by the ANSYS Parametric Design Language, the numerical simulation of the model in uniaxial tension, compression and combination of biaxial tension and compression has been taken in detail , and impact on the change of stress and strain in deformation field by loading process. Thus further reveals the damage rules of the concrete and this model for the simulation of concrete test is reasonable.
