Abstract
In a previous paper (Watts and Ford 1952)‡, it was shown that the true yield stress in plane strain could be derived by compression between smooth parallel dies. In this paper the use of the method to determine yield stress-strain curves of strip material is investigated. The various factors involved are studied, and it is shown that the results can be correlated with those of simple tension and compression. The test forms a practical means for accurately determining the yield stress-compressive strain curve for strip materials in the cold rolling process, and the optimum test conditions are established. The anomalous results found in rolling relatively thick material are demonstrated.Keywords
