The coefficient of friction is an important variable that must be defined to allow the accurate prediction of the forming geometry and stresses involved in metal forming processes. Literature reports have shown that the coefficient of friction does n...

Negative Poisson's ratio: A ubiquitous feature of wood (2023)
Journal Article
Marmier, A., Miller, W., & Evans, K. E. (2023). Negative Poisson's ratio: A ubiquitous feature of wood. Materials Today Communications, 35, Article 105810. https://doi.org/10.1016/j.mtcomm.2023.105810

Most materials contract laterally when stretched axially i.e. they have a positive Poisson's ratio. Negative Poisson's ratios (NPR, also auxetic) are largely limited to single crystals or to artificial meta-materials such as honeycombs, foams and com...
