英文摘要：

A rate-dependent constitutive model for the deformation behavior of amorphous alloys with the effects of hydrostatic-pressure sensitivity and plastically-dilatancy was developed.The constitutive model was implemented in a finite element analysis to study the effects of the voids on the deformation behavior of bulk amorphous alloys by writing a user subroutine in ABAQUS/VUMAT.The mesoscope evolvement law of the deformation was also studied.
