Title:
The Study of Stress State in Indentation of a Flat Punch with Rounded Edge in Axisymmetric Backward Extrusion
Author Name:
Mr. Vaibhav Kumar Singh
Abstract:
ABSTRACT Analytical resolution ought to obtained of contact drawback for indentation of flat punch with rounded edges in axi parallel extrusion to each surface pressure and interior stress fields for a given die form at totally different speed field. each slippery friction and partial slip condition should be finished within the equation of metal flow for extruded material taking into thought vonmises yield criterion and also the sophisticated high elastic contact stress within the flat and rounded edges dies . Associate in Nursing scientific method mistreatment model sample of exposure elastic material for configuration the result of rounded edges on the strain distribution within the contact zone . A numerical methodology used programming for determination the analytical equations of metal flow mistreatment fast basic and scrutiny the theoretical with the experimental results .A kinematic ally admittable metal flow cylindrical speed mistreatment strain rate of plastic flow has been projected to get the load of contact on the elastic punch face throughout the axi-symmetric backward extrusion. The theoretical results predict the forming force , rule of friction , space reduction and also the metal flow quite satisfactorily compared with the experimental results.
