Drawn metal sheet sample forming flow curve depth test procedure uses high speed optical recording of statistical pattern as load is applied through load arms by test stamp

摘要

A drawn metal sheet sample forming flow curve depth test procedure uses high speed optical recording in a load unit (5) with detection of strain representative parameters of a statistical pattern in a central measurement area (2) when a load (5) is applied through attached loading arms (3) by a test stamp (8). Independent claims are included for equipment using the procedure.
