抄録

The forming limit curves (FLC) of 1050-O and 1050-H14 aluminum sheets were determined. The effect of plastic properties of the sheet materials on the FLC was investigated. For determining the forming limits, a slight difference between two methods, the stretch-forming with cut blanks and the hydraulic bulging with an elliptical die was ob- served. The experimental FLCs were compared with the theoretically calculated curves. The FLC is markedly affected by the variation in n-value, however, not affected by the variation in r-value of the material.
