Abstract:

Provided is a mathematical model of stretching operation involving wall thinning of axisymmetric blanks of anisotropic materials. Obtained were correlations which can be used to evaluate the kinematics of the material flow, the stress and strain states of the blank, the force conditions and the limit possibilities of drawing involving wall thinning of thick-walled anisotropic axisymmetric blanks. Comparison of results of theoretical calculation against experimental data have shown satisfactory similarity. The maximal difference between the theoretical and experimental data does not exceed 10 percent. The research results were used in developing the technological process to manufacture thick-walled cylindrical blanks for critical axisymmetric items made of steel 11YUA.
