Auxetic structures have great potential in modern engineering, and their design represents an emerging field industrial applications. The accurate synthesis of the elements such requires multidisciplinary approaches that combine kinematics structural mechanics. Design methodologies are often based on complex time-consuming numerical methods with considerable computational burden for exploring a large set alternatives. aim present work is to propose novel method designing symmetrical auxetic use pseudo-rigid mechanisms can reproduce nonlinear elasto-kinematic behavior limited parameters. For definition these mechanisms, theory kinematic invariants proposed. It allows deduction surrogate rigid-link simpler structure but remarkable accuracy. This approach employed generic analysis compliant and, this study, it extended first time support structures. paper describes analytical process deduce equations discusses example application re-entrant structure, comparing results those flexible multibody model, finite element experimental tests. All comparisons demonstrate proposed methodology, which also be adapted other types
