Heterophases, such as precipitates, inclusions, second phases, or reinforcement particles,
often drive void nucleation due to local incompatibilities in stresses/strains. This results in a …

The generalized stacking fault energies (GSFE) and Peierls stresses are strongly related to
the mechanical properties of refractory metals. In this work, the GSFE curves and Peierls …

We perform molecular dynamics simulations of the nanoindentation on VN (001) films with a
spherical indenter to elucidate the initial plastic deformation and the formation mechanisms …

In this paper the initial stage of nanovoids growth in monocrystal aluminum is studied with
molecular dynamics simulations. The dependencies of critical negative pressure in …

We here reveal the initiation of ductile failure in metals at the nanometer scale by molecular
dynamics simulations coupled with a novel analytical model. This proceeds by the emission …

Atomistic simulation methods are appropriate tools for investigating the dynamics of
dislocations and their interactions with obstacles in metallic materials. In particular …

We investigated with molecular dynamics simulation the mechanical responses of VN (0 0 1)
thin films subjected to indentation with a diamond columnar indenter. We calculated the …

The strengthening of metals by nano-scale obstacles is mainly attributed to the impediment
to glide dislocations offered by these obstacles. It is important to understand the …

Molecular dynamics simulation was performed to study the growth of spherical nano-voids
and the fracture properties of γ-TiAl single crystal. It is found that the emission of shear loops …

In the present work, the effect of a pre-existing nanovoid on multivariant martensitic growth
and in particular, on the phase transformation (PT) threshold stress, is investigated using the …
