In this paper, a parametric study was conducted to investigate the effects of geometric parameters on the energy-absorption capacity of a TSP unit cell under both quasi-static and dynamic crushing. A novel re-entrant TSP unit cell is proposed by introducing the re-entrant edge at its corner to improve the performance of the originally proposed TSP.
