摘要
In this study,the formability of transformation-induced plasticity (TRIP) steel is studied during deep-drawing processes with preforming.The effects of preforming on theminimum thickness of can are investigated with a constitutive model accompanying strain-induced martensite transformation in prestrain condition.The constitutive model has been implemented into ABAQUS/UMAT for analysis of TRIP steel-forming processes.The results show that preforming slightly influences the thickness uniformity of TRIP steel in forming.
