Evaluation of Small Scale Formability Results on Large Scale Parts: Aluminum Alloy Tailor Welded Blanks

This paper investigates the application of standard formability testing results for aluminum alloy tailor welded blanks (TWB) to full size stampings. The limit strains obtained from formability testing are compared to measured strains in a larger scale part. The measured strains in the full scale part are also compared to predictions from finite element simulation.
