The aim of this study is to present two dimensional models of human head undergoing linear acceleration and impact using finite element analysis and validating the results with dynamic impact experiments. The experimental model consisted of a cylindrical gel as brain surrogate material undergoing 55G deceleration with slip boundary condition. Two FE models were developed and compared namely, Lagrangian and Arbitrary Lagrangian Eulerian (ALE). Parameters such as the logarithmic strain and void generated in the posterior region of the head were used to validate the results.
