A Spectral Element Enrichment Wall-Model
Steven R. Brill, Pinaki Pal, Muhsin Ameen +2
We develop an enrichment wall-model within the spectral element method (SEM) framework for large-eddy simulations of wall-bounded flows. The method augments the polynomial solution…
Extended Micromorphic Computational Homogenization for Mechanical Metamaterials Exhibiting Multiple Geometric Pattern Transformations
O. Rokoš, M. M. Ameen, R. H. J. Peerlings +1
Honeycomb-like microstructures have been shown to exhibit local elastic buckling under compression, with three possible geometric buckling modes, or pattern transformations. The in…
Micromorphic Computational Homogenization for Mechanical Metamaterials with Patterning Fluctuation Fields
O. Rokoš, M. M. Ameen, R. H. J. Peerlings +1
This paper presents a homogenization framework for elastomeric metamaterials exhibiting long-range correlated fluctuation fields. Based on full-scale numerical simulations on a cla…
Size effects in nonlinear periodic materials exhibiting reversible pattern transformations
M. M. Ameen, O. Rokoš, R. H. J. Peerlings +1
This paper focuses on size effects in periodic mechanical metamaterials driven by reversible pattern transformations due to local elastic buckling instabilities in their microstruc…
