Perforation of aluminium alloy thin plates
TypeArticles dans des revues avec comité de lecture
Low velocity perforation of aeronautical aluminium alloy sheets 2024 T3 is studied in this paper. After a literature review on recent experiments and models of plate’s perforation, experimental results for 2 thicknesses (2 mm and 4 mm) of plates are presented. Perforation tests are performed with an instrumented drop test. The striker has a large diameter and a conical shape nose. Two models for perforation are presented and calibrated to bring a better understanding of the experiments. The first one is an analytical model based on an energetic approach. The second one is a numerical shell Finite Element FE model. A Johnson Cook phenomenological behavior law of the plate’s material is implemented in the finite element code Abaqus/Explicit. The velocity, the evolution of the impact force, the absorbed energy and the cracks’ propagation are analysed.
