In this work we examine in detail the instability present in the rolling of clad sheets with supplemental results from the clad sheet drawing and tension testing presented as well. Our work clearly demonstrates two important trends that have not been reported before. Namely that the plastic instability present in the rolling of the clads made with two materials with different flow stress is significantly delayed with increasing fraction of the stronger component in the clad and by decreasing roll radius. It is shown that the redundant work is partially responsible for these trends although a modified instability analysis still under predicts the observed results.
