Based on stretch averaging, two non‐affine strain measures for materials with random network microstructure are suggested. The first concept provides a scaling between affine and non‐affine behaviour that is predefined by the network functionality. The second approach applies to fibres that experience strong reorientation upon macroscopic deformation of the network. (© 2014 Wiley‐VCH Verlag GmbH & Co. KGaA, Weinheim)
