Abstract

For three-dimensional cellular beam-and plate-like structures with a triangular microarchitecture, this conference contribution presents a family of two-scale beam and platemodels relying on the anisotropic form of Mindlin's strain gradient elasticitytheoryof form II. Acomputational homogenization method is adopted fordetermining the constitutive parameters of the related classical and higher-order constitutivetensors. Isogeometric conforming Galerkin methods areapplied for solving the beam and plate problems. Numerical examples illustrate the reliability and efficiency of the dimensionally reduced structural modelsand numerical methods–in capturing the bending size effects induced by the microarchitecture, in particular.
