Numerical Simulation of End Friction Effect in Compression Test of Concrete

Abstract:

By using PFC2D a numerical specimen of particle aggregates is established. It achieved consistent mechanical parameters of concrete of C35 with the Code for Design of Concrete Structures(GB 50010-2010) by using PFC2D to simulate concrete compression test and it is proved feasible that PFC2D is suitable for simulating compression tests. End friction effect is studied by changing the coefficient of friction of loading plane. The results show that end friction effect will lead to a small cross section in the central and a large cross-section in the end. The compressive strength will increase with the loading plane friction coefficient increases.
