Abstract

We describe a specialized, in-plane measurement technique that subjects thin sheet metal specimens to longitudinal bidirectional loading. The test provides critical data for validating complex hardening laws for improved springback prediction. All of the principal forces applied to the specimen are measured throughout the test, improving the accuracy of the friction compensation during compression. Initial results demonstrate that this approach is viable and will generate the data necessary to determine directionally dependent changes in the yield behavior (Bauschinger Effect).
