Two recent papers - one related to head impact and the other on orthotropic Kirchhoff plates

These two papers have recently been published in Int. J. Mech. Sci. and Acta Mech.:

1) Analytical Models for the Impact of a Solid Sphere on a Fluid-Filled Spherical Shell Incorporating the Stress Wave Propagation Effect and their Applications to Blunt Head Impacts
