The dynamic crushing behavior of the open-cell aluminum foam with negative Poisson's ratio (NPR) was investigated using the finite-element (FE) method. The plateau stress, the specific energy absorption, and the deformation modes are determined using the FE models. The results indicate that the plateau stress and specific energy absorption …Web

Impact crushing can be of two variations: gravity and dynamic. An example of gravity impact would be dropping a rock onto a steel plate (similar to what goes on into an Autogenous Mill). Dynamic impact could be described as material dropping into a rapidly turning rotor where it receives a smashing blow from a hammer or impeller.Web
