A theory for swaging of discs and lugs
The plane strain compression test is capable of attaining large strain that arise in sheet metal forming practice. The flow data it provides serves as base-line data for numerical simulations of automotive panel forming processes. This test has been adapted, through its tooling, instrumentation and procedure to suit this requirement, each serving the measurement of thickness changes during incremental loading. The analysis admits anisotropy in two rolled sheet automotive aluminium alloys with contrasting flow curves; one smooth the other serrated. Flow curves correlate with simple tension and bulge forming extending the strain range usefully to over 100% strain.
