Cupping test

The cupping test is a test method applied in the metalworking industry and is used to determine the ductility of sheet metals and strips.

For the performance of cupping tests on sheet metal a spherical drawing punch is pressed into a clamped metal sheet until a crack appears. The cupping test is used to assess drawing formability.

Cupping Test Overview

Cupping tests are described in various standards. Here you will find an overview of the current standards and tests.

Cupping test to Erichsen/Olsen

Cupping tests to Erichsen (ISO 20482) and Olsen (ASTM E643) are used to determine the stretching capacity a of sheet metal.

Forming limit curve (FLC)

With a forming limit curve to ISO 12004, the failure limit of a sheet metal can be determined.

Hydraulic bulge test

In a bulge test to ISO 16808 biaxial stress-strain curves are determined using a hydraulic cupping test.
