Safety Zone

To view the plot right click on Forming Results and select Safety Zone from the Formability menu to display a contour plot of 6 possible zones that occur during forming. Clicking on any of the color bars in the right hand scale will highlight that particular zone on the part and de-intensify the other 5 zones. By clicking anywhere else in the Graphics Display Area, the original view with all the regions highlighted will appear again.

• Low Strain - Minimal stretch or compression in either the major or minor directions.
• Strong Wrinkle Tendency - Slight stretch in one direction and compression in the other with material thickening. Wrinkles are very likely to occur.
• Wrinkling Tendency - Stretch in one direction and compression in the other with slight material thickening. Wrinkles may occur.
• Safe - Area below Forming Limit Curve where failure is not likely to occur.
• Marginal - Area between the safe and fail zones where the forming process is marginally safe.
• Fail - Area above Forming Limit Curve where splitting is likely to occur (localized thinning).

Below is a sample plot.
