INVESTIGATE THE BULGING EFFECT OF METALLIC SOLID CYLINDER UNDER COLD UPSETTING USING FINITE ELEMENT ANALYSIS
Abstract: Friction is an integral part of metalworking and manufacturing processes due to the relative motion and forces continually acting on tools, dies, and workpieces. Friction both raises the effort and consumes energy. However, measuring friction is not straightforward and cannot be considered an independent parameter. In many metal-forming procedures, the impact of friction is just as crucial as other quantifiable factors. Various methods have been used to estimate friction, assuming …

Modified Design Improvement Study and Optimization of a intake Manifold to Obtain Unequal Distribution of Velocity for Optimal Diesel Engine Performance
Abstract: Geometrical design of intake manifold has been found very significant for the better performance of an I.C. Engine. It becomes less effective at the intake manifold's runner's outlets due to an uneven flow distribution of the intake air. With an increase in velocity at the distribution channels, the presented study seeks to make this uneven velocity distribution nearly equal without requiring any additional significant changes to the entrance manifold's construction. …
