Abstract : Lightweight honeycomb structures helps in considerable weight reduction in industrial applications. The study investigates the effect of reinforcement on the circular core honeycomb structure under axial compression behavior. The numerical analysis for load carrying capacity is performed using Abaqus-CAE. For experimental validation, steel honeycomb panels (with and without reinforcements) are fabricated by furnace-brazing technology in a continuous furnace. Though the reinforcements increased the panel weight, a substantial increase in the load carrying capacity (44%)) is observed. The results indicate that reinforced honeycomb structure with cell diameter of 10 mm has the highest load carrying capacity. The experimental results validate the developed numerical model.
