Abstract
In the work at hand a three-dimensional mesoscopic model for the compression and recovery simulation of structured nonwovens is presented. Starting point of the model is a one-dimensional power-law, which is extended towards a three-dimensional orthotropic model incorporating the local fiber volume fraction. Furthermore, strain rate dependency of fibrous materials is considered. The presented constitutive model is implemented into the solver FeelMath, which is using the fast Fourier transform to solve the Lippmann-Schwinger equations.
