However, because the main constituent of olivine-rich rocks does not have enough slip systems ... garden wire mesh 13mmPlasticity in a crystal of pure metal is primarily caused by two modes of deformation in the crystal lattice: slip and twinning. Slip is a shear deformation which moves the atoms through many interatomic distances relative to their initial positions. Twinning is the plastic deformation which takes place along two planes due to a set of forces applied to a given metal piece. garden wire screwfix
