Low velocity perforation of an aluminum alloy:experiments and simulations
Low velocity perforation of an aeronautical aluminum alloy sheet 2024 T3 subj ected to impact is studied in this paper. The main objective is to compare experimental results and simulations by analysis of the failure. The perforation test is made with an instrumented 3 meter drop test. The striker has a large diameter (45 mm) and a conical shape. Sheets thickness is 2 mm. The influence of the impact velocity is analyzed. A phenomenological behavior law of the sheets material is implemented in the finite element code Abaqus/Explicit. Thus. 3D simulations of perforation are performed using a damage evolution law and a ductile failure criterion. To understand the phenomenon. the perforation force and the sticker velocity will be analyzed. Simulations are validated by experimental tests and compared with an analytical model.
