Disordered solids are ubiquitous in engineering and everyday use. Although research has
made considerable progress in the last decades, our understanding of the mechanics of …

Hard and brittle materials usually exhibit a much lower strength when loaded in tension than
in compression. However, this common-sense behaviour may not be intrinsic to these …

Disordered materials, like metallic glasses or silicate glasses, have an atomistic amorphous
structure preventing the formation of extended defects such as dislocations. Irreversible …

We develop and extend a method presented by Patinet, Vandembroucq, and Falk [Phys.
Rev. Lett. 117, 045501 (2016) PRLTAO 0031-9007 10.1103/PhysRevLett. 117.045501] to …

Metallic glasses (MGs) possess remarkably high strength but often display only minimal
tensile ductility due to the formation of catastrophic shear bands. Purposely enhancing the …

Based on recent findings in ultrafine grained metals, we proposed a strategy for overcoming
the strength-ductility trade-off in structural metallic materials. Sequential nucleation of …

Shear transformation is the elementary process for plastic deformation of metallic glasses,
the prediction of the occurrence of the shear transformation events is therefore of vital …

In amorphous materials, plasticity is localized and occurs as shear transformations. It was
recently shown by Wu et al. that these shear transformations can be predicted by applying …

A mesoscale numerical model based on shear transformation zone (STZ) theory is
implemented in a commercial finite element software. The model is designed to predict the …

Shear transformation zones (STZs) are widely believed to be the fundamental flow defects
that dictate the plastic deformation of amorphous alloys. However, it has been a long-term …
