Abstract

“Phase transforming cellular materials (PXCMs) are a class of materials whose unit cells exhibit multiple configurations (metastable or bistable) [1]. The geometrical structure of the PXCM can change to increase the energy absorbed. The hysteretic nature of the PXCM makes the potential application of these cellular materials extremely versatile”[1]. The objective was to be able to research within the 3D realm for the purpose of constructing a 3D PXCM.

A well known PXCM has a sinusoidal beam mechanism. During the summer the research group decided to test different geometries, in this case, shells were created with tennis balls.
