Design and Implementation of a Numerical Technique to Inform Anisotropic Hyperelastic Finite Element Models using Diffusion-Weighted Imaging
Abstract
A novel implementation of Diffusion-Weighted Imaging (DWI) into a finite element model is presented for capturing the anisotropic behavior of fibrous materials. The currently available finite element codes do not allow for the incorporation of anisotropic fiber directions that exist in biological soft tissues. The present work describes the continuum theory of transversely isotropic hyperelasticity, as well as the computational methods used to extract fiber directions from medical imaging data.
