Micro Abstract:
The first and second strain gradient elasticity theories, resulting in higher-order governing equations, are studied in the framework of continualization, or homogenization, of lattice structures such as trusses in plane and space, with auxetic metamaterials as a special application. In particular, the role of length scale parameters and classical dimensions, such as the beam thickness, is addressed by parameter studies. Finite element and isogeometric methods are utilized for discretizations.
