In many cases, it is very challenging to evaluate the mechanical behavior of fibrous materials experimentally due to the small dimensions of the specimens. Hence, to predict properly mechanical properties, network-scale models are desired to obtain homogenized material properties by considering fiber-scale mechanisms. The current study demonstrates how three-dimensional representative volume elements for fiber networks can be used within the finite element method in order to investigate the influence of micro-scale properties on the macro-scale material response. Both, current trends and open challenges will be addressed with particular focus on nonlinear material behavior.
