Description: To test forming properties under more realistic conditions technological testing methods are used which simulate the practical process in a simplified form. This interactive animation schematically presents the Erichsen cupping test, which is a simple stretch forming test of a sheet clamped firmly between blankholders to prevent in-flow of sheet material into the deformation zone. The punch is forced onto the clamped sheet with tool contact (lubricated, but with some friction) until cracks occur. The depth (mm) of the punch is measured and gives the Erichsen index 'IE', standardised under DIN 50101.
