Material design of elastic structures using Voronoi cells

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

Design using Genetic Algorithms -- Some Results for Composite Material Structures

This paper reviews an approach to design using Genetic Algorithms as applied to the domain of composite material structures. We first discuss the concept of a Genetic Algorithm (GA) and the role it can play in design, namely as an evolutionary search optimizer based on simulation results. We then discuss the composite structure design problem and how GA’s can be used for design in this domain. ...

Multifunctional Topology Design of Cellular Material Structures

1 This is a revised version of Paper Number DETC2006-99373, published in the ASME Advances in Design Automation Conference. ABSTRACT Prismatic cellular or honeycomb materials exhibit favorable properties for multifunctional applications such as ultra-light load bearing combined with active cooling. Since these properties are strongly dependent on the underlying cellular structure, design method...

Voronoi Grid-Shell Structures

We introduce a framework for the generation of grid-shell structures that is based on Voronoi diagrams and allows us to design tessellations that achieve excellent static performances. We start from an analysis of stress on the input surface and we use the resulting tensor field to induce an anisotropic non-Euclidean metric over it. Then we compute a Centroidal Voronoi Tessellation under the sa...
