Stress Behavior Of Tailor-Welded Blanks For Dissimilar Metals Using Finite Element Method

This paper presents the stress behavior of tailor-welded blanks (TWBs) for dissimilar metals and identifies the critical locations using the finite element method. By using dissimilar metals with different welding configurations, the critical points where the force is concentrated and the maximum f...
