Influence of microstructure on size effect for metamaterials applied in composite structures

Microstructure related deviation from elastic response is known as “size-effect.” Metamaterials – for example modeled by strain gradient elasticity capture this effect adequately means of additional parameters to be determined. We employ a methodology based on asymptotic homogenization in order obtain metamaterials and then present the influence these using simulations. By finite element method, we solve deformation elasticity. The implementation established open-source packages (FEniCS) realistic, composite structure with round oval inclusions.
