A bottom‐up multiscale model approach for describing fiber‐reinforced composites is described by Ameya Rege and Sandeep P. Patil in article number 1900211. In their model, the fibers (for example, carbon nanotubes) are modeled as Euler–Bernoulli beams and the particle matrix (for example, silica aerogel) is modeled as an elastic foundation. Furthermore, a molecular dynamics (MD) model is presented that models and characterizes the nanoscale properties of the composite. The results of this MD model are then transferred to the micro-mechanical model, having physically motivated parameters, which then interprets the macroscopic mechanical behavior of the fiber-reinforced composite.
