ABSTRACT This paper describes a method for predicting how much impact kinetic energy is needed to deform, penetrate, and perforate a shell structures. This method based on strain rate effects, non linear materials, and cross section area reduction. An explicit finite element solver was developed to investigate the relationship between the impactor and target under different impact load cases. The study shows that the impactor can deform, penetrate, and perforate the structure depending on the shape, and the velocity of the impactor besides the material properties of both the impactor and the structure. This paper considers a shell structure response subjected to rigid spherical impactor with a fixed weight at different impact speeds ranging between 10 m/s to 150 m/s.
