Conceptual demonstration of homogenization method. (a) A representative volume element of a fibrous tissue at reference state. All the fibers are undulated and exhibit the same property as the matrix with strain energy function (SEF) W0; (b) When subjected to a macroscopic F̄, some fibers are straightened and show stiffer property with SEF W (r) as in Eq. (2b). (c) The effectively homogeneous material with macroscopic SEF W̄.
