Perforation analysis of S235 steel sheets up to 573 K using experimental and numerical methods
This paper reports on efficient experimental and numerical techniques used in the design of critical infrastructure requiring special protection measures regarding security and safety. The presented results, some of which have already been reported in [1], were obtained from perforation experiments carried out on S235 steel sheets subjected to impacts characterized as moderate velocity (approximately 40–120 m/s). The metal was tested using the Hopkinson Bar Technique and pneumatic gun. The originality of perforation testing consist on using a thermal chamber designed to carry out experiments at higher temperatures. 3D scanners and numerically controlled measuring devices were used for the final shape deformation measurements. Finally, the results of FEM analysis obtained using explicit solver are presented. The full-scale CAD model was used in numeric calculations.
