Abstract

Ballistic requirements in the design of military aerospace components are critical for the structural assessment. Although experimental tests remain fundamental, numerical analyses allow us to simulate such a very complex scenario. However, in order to improve the consistency of such simulations, several aspects have to be considered in detail. The material behavior is a key one: constitutive laws, able to describe the material behavior in terms of hardening, strain rate, damage criteria, temperature, etc⋯, is fundamental. Moreover a detailed validation of numerical results is needed. The analysis of ballistic data (such as the residual velocity and the direction of the bullet after the impact) is only one option, but reliable simulations of damage shape and size are the real target. Therefore the paper will focus on the comparison between the experimental damage and the simulated one using a 3D acquisition of the experimental impacted area. This approach allows us not only to evaluate the damage in the macroscale field but also in the near micro-scale: shape on the border of the damage. © 2011 Published by Elsevier Ltd.
