The Use of a Cellular Strain Injury Criterion and Diffusion Tensor Imaging in a Computational Model of Traumatic Brain Injury

ANISOTROPIC MATERIAL MODEL The white matter is approximated as a nearly incompressible, transversely isotropic material. The transversely isotropic assumption is reasonable for white matter regions with highly aligned axons, such as the corpus callosum, or for small representative volumes of white matter. The constitutive model of a transversely isotropic material is defined in terms of a strain energy functio
