【 摘 要 】

The fiber reinforced metal tubes have been proved to exhibit an excellent crashworthy performance and a high ratio of strength to weight in many experiments. Some theoretical models are promoted to predict the mean crushing force, which benefits the design of these structures. Based on the solution of Wang and Lu, the theoretical analysis is presented in this paper to consider the eccentricity factor, which represents the ratio of the outward part to the total folding length. The agreement between the calculated and experimental data reveals that the analytical model is reasonable.
