Abstract

The research material presented in this paper is a continuation of work done in analyzing impact properties of a biomaterial found in a banana peel. Important energy absorbing characteristics, e.g., plateau stress, locking stress, deformation mode and crushing progression, collapsing mechanism, and crushing stroke of the foam filled (peel) structure are compared with the previously analyzed unfilled composite graded (peel) structure. The addition of foam to the structure smoothens and increases the crushing force, and reduces the global locking strain.
