This research work presents the experimental, and numerical investigation of the Quasi-static indentation behavior of 3D printed honeycomb-based truncated pyramid square Structures. The truncated pyramid square structure was selected for analysis because of its high load bearing capacity. The quasi-static indentation test was carried out in accordance with ASTM D7766/D7766M standards. Force versus displacement curves obtained from the experiments were discussed. By this research, the damage diameter created by the indenter were arbitrary and had no relationship with the material property. Computational simulation was performed to compare with the experimental test results.
