DOI: 10.1016/j.ijmecsci.2019.105401
Abstract: Abstract Shear failure is frequently accompanied by the formation of an adiabatic shear band (ASB) under dynamic loading conditions. It was widely believed that both the thermal softening and stress state exert great influence on… read more here.

DOI: 10.1016/j.triboint.2020.106340
Abstract: Abstract The modified scuffing equations based on the adiabatic shear instability induced by friction effects are postulated. With the present equations, an alternative softening mechanism of the near-surface material undergoing adiabatic shear failure is proposed.… read more here.
