Using a measuring method with high efficiency and quality provides the material's formability. Test how the sheet deforms/strains in different directions before a crack appears.
The stamping tests are conducted using a hydraulic press with a capacity of 1200 tons with a specially manufactured tool för FLC measurements. Measurements are done with seven geometries according to Nakazima geometries to assure a good forming limit curve. The measurements are conducted using ARAMIS which is an optical 3D deformation measuring system that analyzes, calculates, and documents strains. ARAMIS measures displacements of a stochastic pattern on the surface which is sprayed on with an aerosol, the measurement window is 0.01% up to several 100%. ARAMIS measures the deformation using two digital cameras continuously during the forming tests, providing a continuous strain map of the sample until crack.
