A Comparative Study of the Pliability of Separate Auxetic Architectonic Structures by Means of CAD

Abstract

<jats:p>If a lengthened structure gets fat in all directions and the same structure gets narrower when it is pressed, it is an auxetic structure. This happens because these kinds of structures have a negative Poisson's ratio (NPR). In this paper a comparative study of unity patterns of CAD auxetic geometries is presented. A Computer Aided Design library of auxetic geometries will be developed to apply them to architecture. The geometric behavior of the eighteen auxetic separate patterns is tested from the developed library in order to develop a systematic comparison, analyzing properties of these forms, such as their maximum achievable area reductions in relation with the total length of bars of the structure, in order to obtain a growth factor.</jats:p>

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

“…In this research a comparison of CAD separate and 2D geometries of stellated reentrant auxetic patterns is shown. The methodology of the realized research pay attention on develop some stellated reentrant auxetic patterns by means of CAD of three unity geometries and three 2D models, from the knowledge acquires in anterior investigations [13] , patents [14][15][16] and conferences [12,13] , and own researches.…”
