Abstract Scope |
We present a methodology for designing cellular structures through modification of a 2-honeycomb using probability density functions. A 2-honeycomb is a tessellation of the plane composed of a single space-filling prototile which can be created using Voronoi tessellation of sites created using Wallpaper symmetries. While this offers an intuitive method for obtaining interesting mechanical behaviors, the design space is limited by the uniformity of 2-honeycombs. Our method introduces an additional step to this process of structure generation using point-density functions which allow for removal of Voronoi sites resulting in explicit control of local stiffness. Since the site removal is randomized, we end up with completely different structures each time the removal is applied. Through FEA simulations, we show that generated structures created with the same parameters have similar mechanical properties. These structures can be used to modify the infill structure for a 3D printed part to minimize the material usage. |
