【 摘 要 】

The finite element simulation was used to analyze the effect of crystallographic texture on material formability in typical sheet metal forming processes: stretch forming, hole expansion, drawing and bending. It is defined that the best formability (maximum cupping depth, flanging ratio, drawing depth, minimum bending radius) is provided by a rotated cube orientation; the worst - by Goss orientation. Some texture components provide better formability than the isotropic case (rotated cube), some - worse (cube, goss) or close to isotropy (copper, brass or S-orientation).
