Auxetic Star-4 Re-Entrant Lattice Sample · 模型 135174
An Auxetic Star-4 Re-Entrant Lattice is a cellular metamaterial designed with a negative Poisson's ratio (NPR), meaning it expands laterally when stretched and shrinks laterally when compressed. Unlike conventional materials that thin out when pulled, Star-4 re-entrant geometries widen in the transverse direction due to their inward-pointing (re-entrant) star or petal-shaped vertex configuration. This model is a Auxetic Lattice at 50% relative density, sample based on the ASTM D1621 standard. I hope this model will be useful to someone
