Abstract

Sandwich panels are a groundbreaking material structure, prized for their lightweight and strength. The core of these panels is a crucial factor influencing their strength, and in this study, a cylindrical hollow core was used. The main aim is to find the most effective core shape and material for reducing forces, employing simulations to save time and costs. Three tests were conducted: compression, bending, and explosion tests. Compression testing sought cores with the highest yield strength, subsequently utilized in bending and explosion tests. Two core configurations were tested, involving Al 6063-T6 material alone and Al 6063-T6 combined with AISI 1020 material in the hollow section. Core heights of 75 mm, 100 mm, and 125 mm were examined to observe variations in strength. The compression test results included critical data such as yield stress, ultimate stress, plate stress, compressive modulus, and displacement. The Al 6063-T6 - AISI 1020 material with a height of 75 mm displayed the highest strength, yielding 306 MPa. Simulation of the compression test indicated stress concentration on the side between the hollow for the Al-6063-T6 core material, while the core with Al-6063-T6 and AISI 1020 materials showed stress centered on the middle hollow. In the bending test, a bending phenomenon was observed at the center of the sandwich panel, with a yield strength value of 436.70 MPa. In the explosion test, the peak acceleration occurred at 0.2 ms, measuring -19000 G, with a maximum displacement of 9.52 mm
