Summary:

Forming limits are determined by analyzing strain distributions obtained from 0.20.05 inches grids imprinted on blanks by photographic or electrochemical marking techniques. Failure generally occurs in a region of stretch forming where all strains are positive (tensile) in the plane of the sheet. Experimental results derived from laboratory specimens and production automotive stampings indicate a predictable critical strain level beyond which failure is anticipated. The most effective method of increasing the stretching limits is the development of a more nearly uniform strain distribution. Factors controlling this distribution are material strain hardening characteristics, die design, stamping geometry, and lubrication
