WebMar 31, 2024 · An incompressible neo-Hookean material is the simplest model of a nonlinear material, which is widely used in mathematical modeling of the behavior of biological substances and, in particular, in the simulation of brain evolution. Throughout this paper, we assume that the material under study occupies a bounded domain \Omega … WebJan 22, 2024 · The equation can thus be written as: F = -Kx. ... With advancements in material science, neo-Hookean materials have also been identified. A neo-Hookean material is hyper-elastic in nature and, despite being capable of regaining its original state, it does not adhere to Hooke’s Law.
