Element length results for a uniform temperature input of 22 °C
Fig. 6.21
Element area results for a uniform temperature input of 22 °C
displacement. This is a result of the material strain hardening at this temperature
(22 °C).
The forming force from the simulation is given in Fig.

.
As seen, the force increases and reaches a maximum force at approximately
21 mm of displacement, and then, the force begins to decrease. The decrease in
force indicates a material instability point where the material does not have perfect
