The work presented in this paper is a continuation of a study on exploring energy absorbing characteristics of a composite functionally graded structure found in a banana peel [1]. The impact behavior of peel structure under strain rates ranging from 4000 s−1 to 15000s−1 are studied. A modified mathematical model is presented, which calculates the initial dynamic crushing stresses of the structure at different impact velocities. The model outputs are compared with finite element simulations for the initial crushing stress, densification strain, global and local deformation modes, reactive force pulse, and total energy absorbed. A reasonable agreement is found between the proposed model and finite element simulations in determining the initial dynamic crushing stress and total energy absorbed by the structure.
