Stacked-origami mechanical metamaterial with tailored multistage stiffness
Origami-baed metamaterial has shown remarkable mechanical properties rarely found in natural materials, but achieving tailored multistage stiffness is still a challenge. This study proposes a novel zigzag-base stacked-origami (ZBSO) metamaterial with tailored multistage stiffness property based on crease customization and stacking strategies. A high precision finite element (FE) model to identify the stiffness characteristics of the ZBSO metamaterial has been established, and its accuracy isdoi:10.21203/rs.3.rs-849340/v1 fatcat:7ehxhapc4zav3iho2ropsdszou
