Theory of metal forming

Webb5 juni 2012 · Summary INTRODUCTION Slip-line field theory is based on analysis of a deformation field that is both geometrically self-consistent and statically admissible. Slip lines are planes of maximum shear stress and are therefore oriented at 45° to the axes of principal stress. It is assumed that the material is isotropic and homogeneous, WebbThe interaction energy of the metal electron-gas with the metal ions can be ... P. THEORY OF METALS. Nature 157 , 668–669 ...

Webb20 dec. 2024 · The application of finite element analysis has been presented in multiscale metal forming process. A 3D finite element method (FEM) has first been proposed to analyze the deformation mechanism of thin strip cold rolling with the consideration of friction variation in deformation zone. Webb6 dec. 2024 · The formed precipitates were nonshearable, and thus the dislocations would bypass the precipitates in the form of Orowan loops. To verify the reasonability of the assumption of the conventional stress relaxation theory, the activation volume and SRS results obtained by the stress relaxation test and strain rate jump were compared.
