A nonlinear, finite-element, model is used to examine the biodynamic impact response to helmeted and unhelmeted headforms having human response characteristics. The human response headform is modeled as a spherical brain of nearly incompressible material, a covering of linear elastic dura, a linear elastic spherical skull, and a layer of nonlinear scalp material. The helmet system is modeled as...

Magnon scattering studies can play a crucial role in revealing fundamental aspects of magnon physics. Due to the nonlinear nature scattering, such are also important for applications ranging from traditional microwave signal processing novel magnon-based computation. In this work, simulations employing realistic material parameters used demonstrate tunable properties. The changes affected throu...
