Non-linear and non-local transport processes in heterogeneous media: from long-range correlated percolation to fracture and materials breakdown
M Sahimi - Physics Reports, 1998 - Elsevier
We review and discuss recent progress in modelling non-linear and non-local transport
processes in heterogeneous media. The non-locality that we consider is caused by long …

Elasticity of planar fiber networks
XF Wu, YA Dzenis - Journal of Applied Physics, 2005 - pubs.aip.org
A micromechanics model is proposed for the elasticity of planar fiber networks (FNs). The FN
is created by random deposition of linearly elastic straight rods within a region. The rods are …
