The texture inhomogeneity in cross shear rolled grain oriented Si steel was investigated by means of the through thickness texture analysis. For the chosen rolling reductions (55%, 66.5%) and mismatch speed ratios (1.0, 1.1, 1.3), the deformation textures in various thickness layers consist of thre...

Buckling and forming processes of tubes with varying slenderness ratio (ratio of length to diameter) under external hydraulic pressure were analyzed with three-dimensional finite element method (FEM) for studying tube external pressure forming (EPF). Buckling pressures for different tube blanks with...
