The goal of this project is to develop a modelling and simulation technique enabling:
(i)
the generation of nonwoven unit cell models according to a given set of
structure parameters (size, density/grammage, orientation distribution
function, fiber properties, …) and relying on a sophisticated beam
discretization and formulation extended to contact treatment
(ii) the
simulation of the relevant processing steps, i.e. the densification and
bond point genera-tion, whereby, for simplicity, only isothermal
processes are initially considered and the newly formed bond points are
introduced via Dirichlet boundary conditions confining the nonwoven unit
cell
(iii) deformation simulations (uniaxial, biaxial, bending,…)
under due consideration of fiber proper-ties and contact behavior,
validation against experimental data
