Abstract: 提出了一个模拟混凝土断裂过程的细观力学模型,并应用该模型从混凝土的细观非均匀性结构出发,对混凝土试样在单轴和双轴静态载荷作用下的断裂过程进行了数值模拟,给出双轴载荷作用下混凝土的强度包络面。数值模型结果较好地模拟了混凝土试样从裂纹萌生、扩展到宏观裂纹形成的整个断裂过程,与实验结果表现出较好的一致性。
An mesomechanical model that can simulate the fracture process of concrete is proposed and used to study the facture characteristics of concrete under uniaxial or biaxial loadings based on knowledge of heterogeneous structure of concrete at the mesoscopic level. The biaxial strength envelope of concrete is numerically presented and compared well with experimental results. This model is able to capture the complete fracture process of concrete materials that includes the initiation, propagation and coalescence of microcracks as well as cracking patterns associated with different loading stages and loading conditions, which shows good agreement with corresponding experimental results. 还原
