The search for breakthrough in engineering is continuous. Engineers and researchers relentlessly sought for new methods to maximize the utility of the resources that they have access to. Auxetics is one of such endeavors, to elevate the level of safety and performance of its prospective applications, where compression and impact performance are emphasized. Potential of auxetics which derive from the hybridization of re-entrant honeycomb and folded structures was observed by this study; thus, it aimed to further the study on Kirigami Inspired Auxetic and set the groundwork for its future development. Through the use of ANSYS Explicit Dynamics, the compression and impact characteristics of the Kirigami Inspired Auxetic was observed, and its optimum mesh sizes and velocity BCs were identified.
