Chapter 19 Cold_Working Processes - Minimum Bend Radius

In this exercise the work material area ratio Af / A0 can be varied. This can be viewed as changing the work piecec material in the part-process design activity. The minimum bend radius is shown as a function of the corresponding percentage reduction in area.

Click Reset to get an initial value of Af / Ao.
Determine the percent change in minimum possible bend radius if this measure of material ductility is reduced by 10%?

Doing this exercise several times will emphasize an important feature of the material behavior-minimum bend radius description.
