Fundamentals of Metal Forming: Theory of Plasticity - stress tensor – Invariants of stress strain - hydrostatic & deviator components of stress – flow curve – true stress and true strain. Yielding criteria – yield locus – octahedral shear stress and shear strains. Plastic deformations of crystals - critical resolved shear stress. Metal working: mechanics of metal working – working temperature - strain rate effects – friction and lubrication – deformation zone geometry.
Forging and Rolling Processes: Forging process – classification – equipment – calculation of forging loads – forging defects – residual stresses. Rolling: classification - rolling mills - rolling of bars & shapes – rolling forces – analysis of rolling – defects in rolling - theories of hot & cold rolling – torque power estimation.
Extrusion and Drawing Processes: Extrusion: classification - equipment – Analysis of extrusion process - extrusion defects – hydrostatic extrusion – tube extrusion. Drawing: Classification - rod & wire drawing equipment – analysis. Deep drawing – tube drawing – analysis, residual stresses.
Sheet Metal Forming Processes: methods – shearing and blanking – bending – stretch forming – deep drawing – forming limit criteria – defects.
Special Forming Methods: Stretch forming – press brake forming – explosive forming – electro hydraulic forming – magnetic pulse forming – super plastic forming – electro forming – fine blanking - Isothermal forging – HERF.
