Design of Air Booster for 1200 Ton Mechanical Press
Published In: GJRE Part: A: Mechanical & Mechanics Volume: 14 Issue: 1
A mechanical press is used for pressing of sheet metals to give it the desired shape. Mechanical press is a machine that changes the shape of the work piece by applying tones of load on it for accurate output. Mechanical punch presses fall into two distinct types, depending on the type of clutch or braking system with which they are equipped. Generally older presses are "full revolution"...

Effect of Heat Treatment on Crack Initiation & Propagation of Stainless Steel (Ss-304)
Published In: GJRE Part: A: Mechanical & Mechanics Volume: 14 Issue: 1
Cyclic loading is common experimental practice for investigations of large structures like vehicles. Numerical analysis of cyclic loading conditions is also a well-established field of research and application. Theoretical and practical support is rare for evaluating growth of fatigue cracks under cyclic loading conditions. Cracks can occur naturally in engineered components due to combi...
