The compressibility properties of systems consisting of generic rotating rigid triangles are analyzed and discussed. It is shown that these systems which are usually associated with auxeticity can exhibit strongly ani...
1. Introduction The convexity of surfaces is an interesting mathematical topic with application to modeling objects (for example, optical lenses). Conditions for Bernstein-Bézier surfaces defined over triangles to be...
