note = {Crystal plasticity finite element analysis method considering the accumulation of
geometrically necessary (GN) dislocations was applied to monotonic loading of pure magnesium
bi-crystal. The deformation mechanisms considering in the present analysis method are basal slip
, prismatic slip , 1st order pyramidal slip , 2nd order pyramidal slip and tensile
twinning . Tensile twinning is incorporated into crystal plasticity analysis assuming that
twinning plane and direction of shear by twinning are equivalent to slip plane and slip direction,
respectively. Critical resolved shear stresses (CRSSs) for each slip system in the literatures were
used. Analysis model is designed to investigate the influence of grain boundary on the activation
of slip systems. That is, one grain consisting of bi-crystal (grain A) had the crystal orientation
whose Schmid factor for prismatic slip is 0.5. The crystal orientation of the other grain (grain B)
was slightly deviated from that of grain A. The result of the calculation of tensile loading of the
bi-crystal showed that both grains are deformed by the multiple slip of basal slip system, which
resulted in the formation of GN dislocation bands., c (2010) Trans Tech Publications},
