Abstract
Schmid's law is used to predict the tendency of different grain orientations to deform via perfect slip, twinning, intrinsic and extrinsic faulting in a twinning-induced plasticity steel subjected to uniaxial tension. While the Schmid factors for twinning and intrinsic faulting are equivalent, the present analysis underscores the feasibility of twin nucleation at high strains via extrinsic faulting in the near-< 100 >-oriented grains that are nominally regarded as being unfavourably oriented for twinning.
