Comparative study of multiscale computational strategies for materials with discrete microstructures
K. Mikeš, F. Bormann, O. Rokoš +1
The evolution of local defects such as dislocations and cracks often determines the performance of engineering materials. For a proper description and understanding of these phenom…
A Newton Solver for Micromorphic Computational Homogenization Enabling Multiscale Buckling Analysis of Pattern-Transforming Metamaterials
S. E. H. M. van Bree, O. Rokoš, R. H. J. Peerlings +2
Mechanical metamaterials feature engineered microstructures designed to exhibit exotic, and often counter-intuitive, effective behaviour. Such a behaviour is often achieved through…
Level set based eXtended finite element modelling of the response of fibrous networks under hygroscopic swelling
P. Samantray, R. H. J. Peerlings, E. Bosco +3
Materials like paper, consisting of a network of natural fibres, exposed to variations in moisture, undergo changes in geometrical and mechanical properties. This behaviour is part…
Experimental Full-field Analysis of Size Effects in Miniaturized Cellular Elastomeric Metamaterials
S. Maraghechi, J. P. M. Hoefnagels, R. H. J. Peerlings +2
Cellular elastomeric metamaterials are interesting for various applications, e.g. soft robotics, as they may exhibit multiple microstructural pattern transformations, each with its…
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…
Reduced integration schemes in micromorphic computational homogenization of elastomeric mechanical metamaterials
Ondřej Rokoš, Jan Zeman, Martin Doškář +1
Exotic behaviour of mechanical metamaterials often relies on an internal transformation of the underlying microstructure triggered by its local instabilities, rearrangements, and r…
