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 …

Thermal Simulation and an Analysis on an Exhaust Gas of a Teg Model using Fluent
Abstract: As the First law of Thermodynamic says “energy is directly proportional to work done” and law of conservation of energy “Energy can neither be created nor can be destroyed, it can only be transformed from one form to another”. Unfortunately any energy policy that produces improvements in the short term is often one that destroys the environment in the long run. It is a universal truth that no exponential growth …

Seismic Assessment of Reinforced Concrete Structures Coupled with O-Grid Bracing Systems
Abstract: The greatest challenge for structural engineers is to design the structures to be earthquake resistant. Basically, the earthquake-resistant design of reinforced concrete structures is a force-based design. When a structure is designed for seismic resistance, various systems are embedded into the structure so as to resist the lateral forces. One of the systems, which are used for resisting lateral forces, is to provide the structures with different types of bracings. …
