An effective interatomic interaction potential for SiC is proposed. The potential consists of
two-body and three-body covalent interactions. The two-body potential includes steric …

Super‐plasticity of single‐crystal beta‐SiC [111] nanowires for> 200% elongation was
observed by in situ axial‐tensile experiments in a scanning electron microscope. The SiC …

The adiabatic elastic constants (C ij) of cristobalite have been evaluated successfully over
the temperature range of 300–1800 K using the molecular-dynamics method with a …

The mechanism of brittle–ductile cutting mode transition has received much attention over
the past two decades. Due to the difficulties in directly observing the cutting zone during the …

The machinability of hard brittle polycrystalline ceramic has a strong correlation with internal
microstructures and their accommodated deformation behavior. In the present work, we …

A classical bond-order interatomic potential function developed by Tersoff has been applied
to study the structural, mechanical, thermal, vibrational, and surface properties of β-SiC. The …

Molecular-dynamics simulations of crystalline (c), nanocrystalline (nc), and amorphous (a)
silicon carbides and silicon were carried out to investigate their vibrational and mechanical …

The nanomechanical response properties of 3 C-SiC nanowires are investigated using
molecular dynamics simulation with Tersoff bond-order interatomic potential. Under axial …

Second-order elastic constants cannot be applied directly to the study of the mechanical
stability of a stressed material. We derive general expressions for stability criteria by …

We investigate the physical meaning of the intrinsic crack resistance in the Griffith theory of
brittle fracture by means of atomic-scale simulations. By taking cubic SiC as a typical brittle …
