%X The finite element method was adopted to analyze the dumbbell-shaped and plain short-fibre reinforced composites. Emphasis was put on discussing the effect of interface property on strengthening efficiency of two models. The adaptability of dumbbell-shaped short-fibre model was also studied. The elastic-plastic model was used to make the numerical calculation and one layer of interface element was divided so that the effect of interface property was introduced. From the analysis of steel wire reinforced tin composite, it was revealed that the interface property affects the strengthening efficiency of two models heavily. Especially under the condition of weak bonding interface, the dumbbell-shaped short-fibre model could increase the strengthening efficiency greatly. The analysis method and numerical results could be used as a reference to the design of short-fibre reinforced composites.
