纤维混凝土的力学模型分析

由短纤维石子砂子水和水泥等物质复合而成的纤维混凝土材料,其宏观机械性能是诸多细观要素的综合作用结果.根据纤维混凝土宏观拉伸压缩力学性能表现,着重考虑纤维的作用,通过一系列力学模型,对短纤维混凝土增强增韧或降低强度的机理进行了细观研究分析.

Analysis of Mechanical Model on Fiber Reinforced Concrete

Fiber reinforced concrete is consisted of short fiber, sand,aggregation,water, cement and so on. The mechanical properties of the material are a general exhibition of the micro-mechanical properties of its contents and their interaction between each other. Based on the macro-mechanic properties of tension and compress of fiber-reinforced concrete, the analysis emphases are located on the actions of short fiber in the materials. Through a series of mechanical model, the mechanisms of increasing or decreasing material strength are studied in view of microcosmic.
