Improving the initial guess for the Newton-Raphson protocol in time-dependent simulations
Jasper Volmer, Tom W. J. de Geus, Ron H. J. Peerlings
A general linearisation procedure for the consistent tangent of a small-strain visco-plastic material model is presented in this note. The procedure is based on multi-variable line…
Thermal origin of quasi-localised excitations in glasses
Wencheng Ji, Tom W. J. de Geus, Marko Popović +2
Key aspects of glasses are controlled by the presence of excitations in which a group of particles can rearrange. Surprisingly, recent observations indicate that their density is d…
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…
Topology and morphology influences on the onset of ductile failure in a two-phase microstructure
T. W. J. de Geus, R. H. J. Peerlings, M. G. D. Geers
Multi-phase material are frequently applied in a wide variety of products, as they posses a unique set of properties by combining two or more distinct phases at the level of the mi…
