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.
