Design and analysis of an auxetic metamaterial with tuneable stiffness

•A simple methodology for generating auxetic metamaterials with tuneable stiffness is proposed and verified.•The stiffness of the metamaterial could be tuned by using one single parameter of VSF (Variable Stiffness Factor).•The proposed auxetic metamaterials have considerable strength, stability and auxetic behavior.•The potential applications and opportunities of the novel auxetic metamaterial are discussed.
