文摘
- •
Brownian Dynamics dynamics simulations on concentrated hard sphere suspensions, glasses and crystals under oscillatory shear.
- •
Glass shows isotropic displacements under shear, while crystal sliding layers produce anisotropic displacements.
- •
Shear-induced crystallization and crystal reorientation minimizes the energy, stresses as well as particle displacements.
