Description
Summary:The cellular structure, inspired by nature's intricate designs, has emerged as a pivotal area of research with profound implications for future technological advancements. From architecture to materials science, from healthcare to robotics, the integration of cellular structures promises innovative solutions to complex challenges. This research investigates the energy absorption capability and efficiency of cellular structures, specifically focusing on re-entrant honeycomb configurations. By utilizing SolidWorks and ANSYS Workbench, mesh convergence tests are conducted to determine the optimal mesh size, followed by compression tests to evaluate performance under varying volume fractions. The study compares the energy absorption capacity of re-entrant honeycombs with graded lattice structures, aiming to determine their suitability for diverse engineering applications. Findings reveal the potential of re-entrant honeycombs to effectively dissipate energy while maintaining structural integrity. The results provide valuable insights into optimizing design parameters for enhanced energy absorption in cellular materials, facilitating advancements in lightweight structural components with improved energy absorption capabilities.
