We infered that ear formation is ascribed to the directional difference of strains (ε_2 & ε_3) in a blank, which are caused by circumferential compressive stresses and radial tensile stresses in the blank at the early stage of the deep-drawing, and ear must occur in the direction of the blank where the ε_2/ε_3 is minimum. Here, ε_2 is the strain in a gauge of a blank and ε_3 is the strain in radial direction. The directional difference of strains is presumed from the moving of the opperatiye slip systems. The opperative slip systems are decided from the computation of resolved shear stresses in a slip direction [110] on a slip plane (111), in each kind of textures which is shown in Table 1. For (100)[001] texture : From Table 2, ears will occur in directions (ε_3 > ε_2) where the circumferential compressive stresses act in [100] and valleys will occur in directions (ε_2 > ε_3) where the circumferential compressive stresses act in [110]. These ears and valleys coincide with our experiments at all. For other textures; (110)[110]+ (110)[001], (331) [110], (112)[111] + (110)[112] : we can also as well as demonstrate.
