Abstract: Abstract Viscoelasticity in metallic glasses (MGs) is commonly attributed to atomic slips or the activation of local shear transformation events. However, based on our extensive molecular dynamics simulations of creep in MGs, we find that… read more here.

Abstract: Abstract We simulate dynamical mechanical spectroscopy in a Cu64Zr36 bulk metallic glass using non-equilibrium molecular dynamics. Applying several loading conditions (constant volume, longitudinal, uniaxial and isostatic), we find that different elastic moduli have very contrasted… read more here.
