Harvesting Deformation Modes for Micromorphic Homogenization from Experiments on Mechanical Metamaterials
S. Maraghechi, O. Rokoš, R. H. J. Peerlings +2
A micromorphic computational homogenization framework has recently been developed to deal with materials showing long-range correlated interactions, i.e. displaying patterning mode…
Integrated Digital Image Correlation for Micro-Mechanical Parameter Identification in Multiscale Experiments
O. Rokoš, R. H. J. Peerlings, J. P. M. Hoefnagels +1
Micromechanical constitutive parameters are important for many engineering materials, typically in microelectronic applications and material design. Their accurate identification p…
Role of inter-fibre bonds and their influence on sheet scale behaviour of paper fibre networks
P. Samantray, R. H. J. Peerlings, T. J. Massart +2
In fibrous paper materials, an exposure to a variation in moisture content causes changes in the geometrical and mechanical properties. Such changes are strongly affected by the in…
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…

Asymptotic homogenization of hygro-thermo-mechanical properties of fibrous networks
E. Bosco, R. H. J. Peerlings, M. G. D. Geers
The hygro-thermo-expansive response of fibrous networks involves deformation phenomena at multiple length scales. The moisture or temperature induced expansion of individual fibres…
Hygro-mechanical properties of paper fibrous networks through asymptotic homogenization and comparison with idealized models
E. Bosco, R. H. J. Peerlings, M. G. D. Geers
This paper presents a multi-scale approach to predict the effective hygro-mechanical behaviour of paper sheets based on the properties of the underlying fibrous network. Despite th…
