【摘要】 混凝土是一种典型的非均匀准脆性材料,其断裂过程是非常复杂的.评述了混凝土断裂以及断裂过程研究的进展状况,主要总结了一些研究混凝土断裂的宏观力学方法和模型,介绍了从混凝土的细观层次出发模拟其断裂过程的数值模型.最后,简单介绍了作者用细观数值方法模拟混凝土宏观断裂过程的研究成果.更多还原

【Abstract】 Concrete is a typical heterogeneous quasi-brittle material used in engineering, and its fracture process is very complex. Main progresses on the study of the fracture and fracture process of concrete are reviewed, a few numerical methods and models used to simulate the fracture process of concrete at macroscopic or mesoscopic level are discussed. At last, the mesomechanical model proposed by authors for simulating the macroscopic fracture process of concrete is briefly introduced.更多还原
