Optimized Engineering Structures With Auxetic Cells
Abstract: ABSTRACT The invention in its various embodiments discloses a structural member(100) designed for improved load bearing usingauxetic expandable‐collapsible structural units(110). The auxetic structural units may have parallel-sided surfacesoriented at an angle (α) to the horizontal direction.In some embodiments the angle varies between 40-140 degree within a layer.The structural member may include at least two layers having identical structural units, the layers varying inorientation αof the structural units, or material or wall thickness thereof. In various embodiments, the angular orientation αmay be the same in alternate layers.The structural member(100) provides load bearing capacity of a solid component at 30-40% of material weight. The invention discloses an optimized structure with structural units oriented alternately at α values of 45° or 135°. FIG. 1
