Finite Element Analysis of Aluminium and Stainless Steel Perforated Sheet Metal (PSM) for Sheet Bending ProcessBy Kartik D Kothari, R. L. Jhala
Abstract: This research work deals with the experimental and finite element analysis of the perforated sheet bending process of stainless steel and aluminium material. Several experiments were performed to investigate the effects of above described variable on stress and load displacement graphs for the tested and simulated components. On the basis of different simulations being carried out with different combinations of material, shape and shape of perforations; the stress analysis was …

Parametric Investigation of Deep Drawing Process for Different Materials: A ReviewBy Kartik D Kothari, R. L. Jhala
Abstract: A process known as Deep Drawing is used to force the metal sheet to flow between punch’s surfaces and die. Thus it is a process of Transformation of Shape with material retaining. A part is said to be deep drawn if the depth of the part is at more than half of its diameter. Number of defects can occur in the deep drawn product. There are several parameters which affects …

Design of Sleeve for Multi-barrel Pellet Injector System: A ReviewBy Krutarth Kumar Reddiar, Kartik D Kothari
Abstract: A multi-barrel pellet injector system has been developed for plasma fueling of the tokamak fusion test reactor (TFTR). This paper describes the different arrangement of barrels along with design of sleeve for holding the barrels, for production and acceleration of pellets of different sizes. The in situ pipe gun concept with the use of compact cryo-coolers enables stable operation as a fundamental facility in plasma experiments. Pellets are accelerated in …
