Drawing Capability of High Formable Packaging Steel: Comparison of Limiting Drawing Ratio and Forming Limit Curve

To assess the suitability of different packaging steels for complex deep drawing applications, nowadays, total elongation and Lankford coefficients in simple tensile tests are used. However, use uniaxial is not supposed to predict limiting ratio precisely thus applications. At same time, conduction experiments extensive requires a high testing effort. Therefore, this work, correlation between forming limit curve results were compared formability steel by much simpler criterion. approaches calculate plane strain test data used capability steel. Results revealed strong measured at fixed blank holder force. calculation methods based on able sufficiently.
