摘要
建立能够描述静水压力影响和塑性体积膨胀的率相关的大块非晶合金本构模型.通过编写ABAQUS材料用户子程序VUMAT,对含不同形态孔洞的Zr基大块非晶合金的变形行为进行有限元分析,并对其细观变化规律进行研究.
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.
