Numerical analysis on rotary forging mechanism of a flange

Gang LIU , Shijian YUAN , Mingxue ZHANG , Longbiao CHI

材料科学技术(英文)

A numerical simulation on the rotary forging process of a flange is conducted by three-dimensional rigid-plastic finite element method. The states of stress and strain rate in the workpiece are analyzed and the forging mechanism of the flange is revealed. Moreover, the influence of the die configura...

Through Thickness Variation of Cross Shear Rolling Texture in Grain Oriented Silicon Steel

Gang LIU , Liang ZUO , Fu WANG , Xiang ZHAO , Zhide LIANG

材料科学技术(英文)

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...

External Pressure Forming and Buckling Analysis of Tubular Parts with Ribs

Gang LIU , Xuelian YIN , Shijian YUAN

材料科学技术(英文)

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...
