S. Ogata et al., Molecular dynamics estimation of shearing deformation properties of alpha-silicon nitride single crystal, MATER T JIM, 40(11), 1999, pp. 1262-1268
Shear deformation properties of alpha-silicon nitride single crystal are in
vestigated by molecular dynamics. Three cases of shearing directions are an
alyzed, two of which were reported to be slip system an the basis of experi
mental observations. The simulation results show that for the experimentall
y predicted slip system, shear strength is low and localized band-like shea
r deformation appears. Disordered atomic structure produced by shear deform
ation is regarded to be amorphous.
