Composite materials are increasingly used in different industries to develop new innovative products. This trend is supported by the tailoring flexibility of composite materials that can lead to desired system-scale performances. The challenge is, therefore, to set up a design framework that relates micro-scale proprieties to structural components behaviors. An important building block passage of this framework is the bridge between micro-scale and meso-scale through micromechanical models, especially in the case of a realistic non-linear behavior. Thus, this work is devoted to shedding light on composite design strategies and recently developed software in this field. In light of this overview, micromechanical models in the nonlinear case are discussed and routes for their improvement are stressed out.
