Abstrait:

As concrete is a heterogeneous material. There is a combination of weak interface – interface in the concrete. From the point of view of mechanics analysis, the interface exists in the combination of materials within the boundary [1]. For ordinary concrete, damage often occurs from the junction interface. The analysis of concrete materials and ist stress distribution near the interface has vital significance. In fact, the boundary condition on the interface, and mutual constraint represent the deformation of the fiber and concrete. The constraints cause stress concentration of interface and nearby interface geometry mutations where stress concentration is very serious. In the elastic range, the stress point at some point tends to infinity, called a singularity. At the same time, due to material composition by multiphase materials, there are a lot of micro cracks at the interfaces. The study of the interface crack model and the materials of the singularity has an important means for the material's performance.
