Abstract Scope |
Materials with a negative Poisson ratio are known as auxetic materials. The advanced membrane Graphene Oxide exhibits auxetic like behavior, how it showcases a negative Poisson ratio is currently unclear to us. A rotating pattern of Graphene Oxide is proposed to explain and illustrate the auxetic nature of the membrane to understanding its properties. However, it is near impossible for us to visualize the formation and moment of the Graphene Oxide while the material is being stretched. Rectangles of different length to width ratios and, a body consisting of polygons and triangles are proposed to illustrate the auxetic nature of the material through non-homogenous shapes. A Solidworks model will be used to simulate the fundamental structure and movement of the Graphene Oxide membrane. The varying shapes and sizes of the Graphene Oxide sheets are observed and captured using an Optical Microscope and analyzed through machine learning. |
