dc.description.abstract | Auxetic structures exhibit unusual changes in size, expanding laterally upon stretching
instead of contracting. This paper presents this effect in a failsafe mode in structures made of rigid
squares. We applied the concept of auxetic structures made of rigid rotating squares (from Grima
and Evans) and offer a novel solution for connecting them. By introducing axes of rotation on the
surface of the squares, a reliable working system is obtained, free from stress, in which the squares
can come into contact with each other and completely cover the surface of the structure, or, in the
open position, form regularly arranged pores. Herein, we present a new 2D auxetic metamaterial
that is mathematically generated based on a theoretical relationship of the angle between the edges
of a square and the position of the axis of rotation. Physical models were generated in the form of a
planar structure and in the form of a circular closed structure. Such physical models confirmed our
initial considerations and the geometrical relationships, offering new application possibilities. The
novel structure that was designed and manufactured for the purpose of the paper can be considered
as a new proposal in the market of auxetic materials. | pl_PL |
