The grain size, and therefore the grain boundary density, is known to play a major role in the
flow stress of metallic materials. A linear relationship to the inverse of the square root of the …

We apply several recently introduced projector-augmented wave, ultrasoft, and norm-
conserving pseudopotentials (PPs) to the calculation of the elastic constants of beryllium …

Using the projector-augmented wave method within the generalized gradient approximation,
a systematic first-principles calculation for energy vs. volume (E–V) equations of state …

A long-standing question is why Poisson's ratio ν nearly always exceeds 0.2 for isotropic
materials, whereas classical elasticity predicts ν to be between− 1 to 1 2. We show that the …

We report a ductile β-type titanium alloy with body-centered cubic (bcc) crystal structure
having a low Poisson's ratio of 0.14. The almost identical ultralow bulk and shear moduli …

Materials synthesized by deposition techniques are often plagued by high levels of residual
stress. While the origin and control of this stress in thin (sub-micron) films has been an active …

We construct a family of beryllium (Be) multiphase equation of state (EOS) models that
consists of a baseline (“optimal”) EOS and variations on the baseline to account for physics …

The lower bound customarily cited for Poisson's ratio ν,− 1, is derived from the relationship
between ν and the bulk and shear moduli in the classical theory of linear elasticity. However …

A systematic investigation of the alkaline earth hydrides Be H 2, Mg H 2, Ca H 2, Sr H 2, Ba
H 2, the corresponding deuterides, and their antecedent metals is reported. We calculate …

Machining high-performance engineering materials, faces challenges including low
machining efficiency, poor workpiece surface integrity and rapid tool wear, which restrict …
