Reduced order modeling for micromorphic computational homogenization of mechanical metamaterials with patterning fluctuation fields
Theron Guo, Ondřej Rokoš
Mechanical metamaterials owe some of their exotic effective properties to microstructural instabilities such as buckling and pattern transformation. Their fine-scale geometry, comb…

A Quasicontinuum Method with Optimized Local Maximum-Entropy Interpolation and Heaviside Enrichment for Heterogeneous Lattices
Benjamin Werner, Ondřej Rokoš, Jan Zeman
Lattice systems are effective for modeling heterogeneous materials, but their computational cost is often prohibitive. The QuasiContinuum (QC) method reduces this cost by interpola…
