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…
Fracture initiation in multi-phase materials: a systematic three-dimensional approach using a FFT-based solver
T. W. J. de Geus, M. Cottura, B. Appolaire +2
This paper studies a two-phase material with a microstructure composed of a hard brittle reinforcement phase embedded in a soft ductile matrix. It addresses the full three-dimensio…
Systematic and objective identification of the microstructure around damage directly from images
T. W. J. de Geus, C. Du, J. P. M. Hoefnagels +2
An original experimental approach is presented to automatically determine the average phase distribution around damage sites in multi-phase materials. An objective measure is found…
Microstructural modeling of ductile fracture initiation in multi-phase materials
T. W. J. de Geus, R. H. J. Peerlings, M. G. D. Geers
The precise mechanisms underlying the failure of multi-phase materials may be strongly dependent on the material's microstructural morphology. Micromechanical modeling has provided…
Microstructural topology effects on the onset of ductile failure in multi-phase materials - a systematic computational approach
T. W. J. de Geus, R. H. J. Peerlings, M. G. D. Geers
Multi-phase materials are key for modern engineering applications. They are generally characterized by a high strength and ductility. Many of these materials fail by ductile fractu…
Fracture in multi-phase materials: why some microstructures are more critical than others
T. W. J. de Geus, R. H. J. Peerlings, M. G. D. Geers
Our goal is to unravel the mechanisms that lead to failure of a ductile two-phase material - that consists of a ductile soft phase and a relatively brittle hard phase. An idealized…
Fracture initiation in multi-phase materials: a statistical characterization of microstructural damage sites
T. W. J. de Geus, J. E. P. van Duuren, R. H. J. Peerlings +1
Understanding the microstructural influence on the failure mechanisms in multi-phase materials calls for the identification of the worst-case scenario. This necessitates a statisti…
Finite strain FFT-based non-linear solvers made simple
T. W. J. de Geus, J. Vondrejc, J. Zeman +2
Computational micromechanics and homogenization require the solution of the mechanical equilibrium of a periodic cell that comprises a (generally complex) microstructure. Technique…
A finite element perspective on non-linear FFT-based micromechanical simulations
Jan Zeman, Tom W. J. de Geus, Jaroslav Vondřejc +2
Fourier solvers have become efficient tools to establish structure-property relations in heterogeneous materials. Introduced as an alternative to the Finite Element (FE) method, th…
