Mesoscopic and multiscale modelling in materials

J Fish, GJ Wagner, S Keten - Nature materials, 2021 - nature.com
The concept of multiscale modelling has emerged over the last few decades to describe
procedures that seek to simulate continuum-scale behaviour using information gleaned from …

Metal forming beyond shaping: Predicting and setting product properties

AE Tekkaya, JM Allwood, PF Bariani, S Bruschi, J Cao… - CIRP Annals, 2015 - Elsevier

The archetype-genome exemplar in molecular dynamics and continuum mechanics

MS Greene, Y Li, W Chen, WK Liu - Computational mechanics, 2014 - Springer
We argue that mechanics and physics of solids rely on a fundamental exemplar: the
apparent properties of a system depend on the building blocks that comprise it. Building …

Resolving the diffusionless transformation process of twinning in single crystal plasticity theory
