環(huán)氧樹(shù)脂基混凝土細(xì)觀結(jié)構(gòu)數(shù)值模擬與性能分析
[Abstract]:A new type of bridge deck paving material, epoxy resin based concrete, was studied at the meso-level, which was regarded as a composite composed of aggregate and epoxy resin matrix two-phase medium. The geometric model of two-dimensional polygonal aggregate distribution of materials is simulated by Monte Carlo method, and the numerical simulation is carried out on Ansys/Ls-Dyna and Hyper Mesh platforms. A similar numerical model is established according to the gradation of the test and the quasi-static compression analysis is carried out. The elastic modulus and compressive strength of the material are obtained. The numerical results are compared with the experimental results. The results show that the numerical model is in good agreement with the experimental results in the calculation of elastic modulus and compressive strength of the material, and the crack propagation form of the material can be well represented by the numerical model.
