Experimental and Numerical Investigation of Forming Limit Diagrams during Single Point Incremental Forming for Al/Cu Bimetallic Sheets

Metals
This article investigated the formability of aluminum/copper bimetal sheets during single-point incremental forming. First, the two-layer sheets were produced by the explosive welding process; then, the rolling process was performed with 50% strain on ...

Aluminum Alloy Sheet-Forming Limit Curve Prediction Based on Original Measured Stress–Strain Data and Its Application in Stretch-Forming Process

Metals, 2019
A new method, by directly utilizing original measured data (OMD) of the stress−strain relation in the Marciniak−Kuczynski (M−K) model, was proposed to predict the forming limit curve (FLC) of an aluminum alloy sheet.
