In order to improve the properties of metallic glasses (MG) a new type of MG structure,
composed of nanoscale grains, referred to as nanoglass (NG), has been recently proposed …

Experiments show an intriguing brittle-to-ductile transition on size reduction on nanoscale
metallic glasses (MGs). Here we demonstrate that such phenomena is linked to a …

We use large-scale molecular-dynamics simulations to investigate the deformation and
failure mechanisms associated with tensile loading of 50 nm diameter Cu64Zr36 …

We report the observation of spiral fracture of the metallic glass Zr 41 Ti 14 Cu 12.5 Ni 10 Be
22.5 (at.%) subjected to both shear and normal stresses. The spiral angle (that between the …

Molecular dynamics simulation is a significant technique to gain insight into the mechanical
behavior of nanostructured (NS) materials and associated underlying deformation …

We proposed an eccentric ellipse criterion to describe the failure of amorphous materials
under a combination of normal stress σ and shear stress τ. This criterion can reflect a tension …

Metallic glasses are topologically disordered down to the atomic scales. As a result, during
mechanical deformation there are random atomic displacements which necessarily lead to …

In the present contribution intrinsic and extrinsic size effects on the shear band propagation
behavior in metallic glasses are studied. To this end, a thermodynamically consistent finite …

Metallic glasses (MGs) have aroused great interest due to their exceptionally high strength
and elasticity, remarkable fracture toughness and attractive processing potential, all of which …
