We investigate the fast β- and Johari–Goldstein (JG) β-relaxation processes, along with elastic scattering response of glass-forming (GF) liquids boson peak, in a simulated Al–Sm GF material exhibiting fragile–strong (FS) transition. These dynamical processes are universal “ordinary” fluids collectively describe their “fast dynamics,” we find these relaxation also arise liquid FS String-like pa...

Contact calculation is of great importance in predicting the material removal (MR) flexible grinding process (FGP). The contact mostly considered approximately constant existing MR models, while situations that varies a lot after FGP are ignored. Therefore, novel model proposed this paper to take those into consideration. Firstly, nonconstant-contact situation introduced. Then, an equivalent me...
