GB/T 4156-2007
AbolishedMetallic materials - Sheet and strip - Erichsen cupping test
金属材料 薄板和薄带埃里克森杯突试验
Application Summary AI generated
This standard specifies the method for conducting the Erichsen cupping test on metallic sheet and strip materials. It is applied in the metallurgical and manufacturing industries to evaluate the formability and ductility of thin metal sheets, particularly for quality control in stamping, deep drawing, and automotive body panel production. The test measures the material's resistance to cracking under biaxial stretching conditions.
