Abstract
A cooking vessel includes a base having a flat bottom and a sidewall connected to and surrounding the base, thereby defining an interior space configured for containing food. The base comprises a layered composite material that includes a first layer of the composite material has a positive Poisson's ratio (PPR) and a second layer of the composite material is disposed in contact with the first layer. The cooking vessel includes a material having a negative Poisson's ratio (NPR).
