Sheet Metal Stamping Simulation

“The comparison between the original and final thickness converted to strain readings and plotted on thickness strain diagrams. The thickness is measured by pointed micrometers, or by ultrasound gage. From the final thickness and original thickness ratio, TF / TO, an actual strain level can be developed based on constant volume and plotted on a thickness strain diagram.” (Hogarth, D.J., Gregoire, C.A., Caswell, S. L., 1991, p. 88).
