The aim of this research is to analyse the theory of honeycomb structures, their pros and cons among other structures. To implement it in the physical realm, a honeycomb structure was analysed and evaluated with various modifications in SolidWorks to determine the efficiency of the structure. Honeycomb structures were evaluated for static structural and deformation with varied inclinations to the perpendicular axis to the base, and it was determined that the original structure was the most efficient, as it suffered the minimum stress of all the structures. Different cell geometries, such as triangles, squares, and pentagons, were tested, and it was discovered that the hexagonal structure had the best strength-to-weight ratio of all the configurations. For further analysis, the hexagon cell geometry was changed by adding chamfers and inner radius to see if there were any differences in the overall structure. It was found that the construction with a radius of 0.5 mm was more efficient at managing stress than the original structure due to its higher stress to weight ratio. The structure was optimised, and a model was built. The findings indicate that the optimised structure with the inner radius had a strength/weight ratio of 4.3% more than the original structure. The stress after impact test revealed a 5% reduction in stress compared to the original construction. The displacement was also determined using the static structural analysis of the same weight and was found to be less than 4% of the original structure.
