Tensioned Auxetic Structures Manual Calculus

Abstract

Auxetic materials have several properties very useful to be applied to architecture structures. This paper is aimed to test structurally a specific auxetic structure model. This hypothesis will be check: if auxetic materials have innovative properties in nanoscale then they will also have these properties in macroscale. But there are some differences for these different scales. In the nanoscale auxetic structures have rigid knots with flexible bars, but in the scale of architecture they will have articulated knots and a cable that stabilizes the set.A unity of the hexagonal re-entrant structure will be tested in order to obtain their structural characteristics. The application of this structure and their behavior in architecture are not yet known, that’s why this auxetic model will become an experimental model to establish a structural evaluation of one of the most innovative auxetic geometries, to apply to the construction of new architectures. The results of research and investigation will become apparent by their structural evaluation, through the utilization of manual calculus.The re-entrant hexagonal geometry provides a strong foundation for research of application of new structural systems on the production of architecture, while identifying transformations that new geometries and their application techniques, will contribute to the development and divulgation of new spatial and typological solutions. That is the reason to claim a detailed analysis to advance on the design and construction of new architectures.

Geometric Study of Two-Dimension Stellated Reentrant Auxetic Structures to Transformable Architecture

“…Novel manufacturers have been designed by the utilization of auxetic patterns. Minimally invasive implantable devices, morphological structures of the forms and smart expandable actuators are the main areas of application [6] . Devices utilized for the development of drop-down satellite antennas like shape memory auxetics alloys (SMA) also exist [7] .…”
