To crack, or not to crack: How hydrogen favors crack propagation in iron at the atomic scale
Aleksei Egorov, Lei Zhang, Erik van der Giessen +1
Steel is a key structural material because of its considerable strength and ductility. However, when exposed to hydrogen, it is prone to embrittlement. Mechanistic understanding of…
Atomistic fracture in bcc iron revealed by active learning of Gaussian approximation potential
Lei Zhang, Gábor Csányi, Erik van der Giessen +1
The prediction of atomistic fracture mechanisms in body-centred cubic (bcc) iron is essential for understanding its semi-brittle nature. Existing atomistic simulations of the crack…
Discrete Dislocation Dynamics Simulations of Nanoindentation with Pre-stress: Hardness and Statistics of Abrupt Plastic Events
Hengxu Song, Hakan Yavas, Erik Van der Giessen +1
The yield surface in crystal plasticity can be approached from various directions during mechanical loading. We consider the competition between nanoindentation and tensile loading…
Study of size effects in thin films by means of a crystal plasticity theory based on DiFT
Surachate Limkumnerd, Erik Van der Giessen
In a recent publication, we derived the mesoscale continuum theory of plasticity for multiple-slip systems of parallel edge dislocations, motivated by the statistical-based nonloca…
Stiffening of semiflexible biopolymers and cross-linked networks
T. Van Dillen, P. R. Onck, E. Van der Giessen
We study the mechanical stiffening behavior in two-dimensional (2D) cross-linked networks of semiflexible biopolymer filaments under simple shear. Filamental constituents immersed…
