Abstract

The purpose of this article is to assess the state of knowledge in terms of modeling and predicting the elastic behavior of flexible composites that exhibit a usable range of deformation much larger than those of conventional polymer-based composites. Two groups of flexible composites based on the reinforcement type are reviewed: (i) The composites consist of straight unidirectional continuous fibers in an elastic matrix. The lamina is treated as a homogeneous orthotropic elastic continuum. Finite elasticity forms the basis of analyzing the nonlinear elastic behavior, including the effect of fiber reorientation. (ii) These composites are made up of an elastic matrix reinforced by textile-like structures including fabric composites and soft biological tissues. Local nonhomogeneous deformation often occurs within the composite because of the internal architecture rearrangement of the reinforcements. One of the desired analysis approaches for these materials is to develop an equivalent continuum model representing the mechanical behavior through a unit cell. In such analysis, new parameters representing the internal architecture rearrangement under loading are usually introduced in the homogenized constitutive equations.
