Abstract

The finite element method (FEM) is a way of solving partial differential equation on a spatially (and temporarily) discretized model. It is widely used in medical applications. In this research, we develop a tool to calculate the response to an impact on human head and brain. We use the finite element method to model the solid tissue as linear elastic materials and the fluid-filled (1) as impressible viscous fluid. The geometric (2) model is derived from Magnetic Resonance Imaging (MRI) data of a real subject. To solve the nonlinear dynamic problem, we use the Newton-Raphson method, and employ parallelization to speed up the computation. Example simulations demonstrate the validation of the model.
