This paper shows that it is inappropriate to relate the angle between the loading axis and the shear-band (or fracture) plane in metallic glasses under uniaxial loading conditions to the coefficient of internal friction in the Mohr-Coulomb model. Shear bands in metallic glasses are a result of mater
Catastrophic failure along a dominant shear band sets the limit on how much plasticity can be achieved in metallic glasses (MGs) under uniaxial compression. Here we show that this instability process is governed by a single system parameter, called the shear-band instability index (SBI), which is pr
The characteristic dimensions of the hot, liquid zone behind a moving shear-band front in a metallic glass are analyzed. In addition to the expected dependence on material constants, the thickness of the zone is proportional to the shear offset, while its width is proportional to the square of the o
