Abstract

Introduction

Transformable architecture heavily depends on grasping geometry. Some natural materials possess geometric traits leading to similar structural responses when their size changes, resulting in diverse spatial shapes. Auxetic materials demonstrate a negative Poisson's ratio, enabling them to shift from lines to surfaces, and from surfaces to volumes or spatial frameworks. The background of this research focuses on evaluating and establishing honeycomb reentrant auxetic geometries to craft innovative architectural spaces capable of transformation. By methodically examining the geometric attributes of these structures at both molecular and macroscopic levels, they could play a crucial role in architectural development.

Method

The method of this investigation entails a comparative Computer-Aided Design (CAD) study of 2D honeycomb reentrant auxetic patterns. The objective is to employ CAD to gain deeper insights into these patterns for architectural applications.

Result

As a result, the study evaluates the geometric performance of various 2D honeycomb reentrant auxetic patterns, systematically comparing them based on criteria such as the maximum achievable area reductions relative to the total length of the structure's bars.

Conclusion

The conclusion is to ascertain a growth factor for these structures.
