Huajian Gao

TL;DR: Gao et al. as mentioned in this paper presented an overview of some recent studies conducted at Brown University on the mechanics of cell-nanomaterial interactions, including the modelling of nanoparticles entering cells by receptor-mediated endocytosis and coarse-grained molecular dynamics simulations.

TL;DR: In this paper, a dislocation dynamics-cohesive zone model is proposed to investigate whether a pre-existing crack in a ductile layer of a composite structure will blunt or rather propagate in a brittle fashion.

TL;DR: Gao et al. as mentioned in this paper developed large scale molecular dynamics simulations of grain boundary diffusion wedges to clarify the nucleation mechanisms of parallel glide in thin films, which is consistent with both continuum theoretical and experimental studies, but also revealed the atomic processes of dislocation nucleation, climb, glide and storage in grain boundaries.

TL;DR: In this article, the authors developed a theory of controlled fragmentation in axisymmetric core-cladding and plane-strain film-substrate systems, which reveals that the process is governed by a reverse shear lag effect which gives rise to a peak tensile stress leading to controlled fragmentation near the necking zone.
