Research on Integrated Strength Ratio and Its Dynamic Variation Law of Laser Tailor-welded Blanks

Sun Dongji Lin Jianping Liu Ruitong Hu QiaoshengTongji University,Shanghai,201804  
During the tailor-welded blanks(TWBs) forming process,the change of thickness and hardening ability of sheet metal are becoming different in the deformation process,which will result in the dynamic variation of strength difference of base metals.Based on comprehensive consideration of the influence of these two factors on the strength difference of base metals,a theoretical model of integrated strength ratio of laser TWBs was proposed,and its explicit expression was established.On the basis of theoretical research on the constitutive relation of laser TWBs in plane strain state,the dynamic changing law of the integrated strength ratio of laser TWBs with different thickness and strain state of the weak base metal was studied under three typical straining states.And the influencing law of thickness ratio of TWBs on the strength difference of base metals was obtained,which will provide theoretical reference for the further researches of the formability of TWBs.
