چکیده
The prevailing risk factors and explosion scenarios in Electric Vehicles (EVs) necessitated this research to focus on the analysis and optimization of auxetic patterns encompassing re-entrant, double re-entrant, and triangular structures under blast loading conditions. In this study, a comprehensive blast analysis has been conducted numerically using ABAQUS on auxetic meta-materials featuring re-entrant, double re-entrant, and triangular structures with varying strut angles (85°, 80°, 75°) and strut thickness. Their performances have been compared among them and also with a traditional solid plate. Among these auxetic structures, the double re-entrant structure with 85o strut angle and 0.2 mm strut thickness outperformed other auxetic structures with a minimal bottom plate displacement of 3.4 mm and plastic dissipation energy of 0.171 kJ. The consistent behavior of these structures has been substantiated by conducting blast analysis with a reduced stand-off distance of 30 mm. The simulation results are then compared with the results of the 50 mm stand-off distance for deformation, plastic dissipation energy, and velocity.
