Finite Element Analysis of Rectangular Plate of S460J2 With Multiple Circular Holes
Abstract: Stress concentration is the main root cause of failure of multi-hole plates in bi-axial loaded conditions. Therefore it is essential to study such Stress Concentration Factors (SCF) to achieve the failure criteria. The method used for analysis is FE analysis. The main cause of increment in the stress is the geometrical irregularity, which may be caused by the various machining operations. Some kind of operations also requires such irregularity for …

Dynamic Analysis of a Multi-geared Rotor Shaft System
Abstract: Gear systems are the toothed members in which the main aim is to transmit power or motion between two shafts by meshing without any slip. Motion and power transmitted between the shafts are kinematically equivalent to power or motion transmitted between frictional wheels. Vibration of gear system causes unwanted noise such as gear whirling. Noise and vibration signals from machine can contain vital information about the internal processes and provide …

Predictive Model on Constant Pressure Drop Variable: Area Fluid Flow System in a Pipe
Abstract: The effect of density, pressure drop, and orifice area was examined in this research. The basic equation developed to represent steady-state fluid flow is the Bernoulli equation which assumes that the total mechanical energy is conserved for steady incompressible, in viscid, isotherm flow with no heat transfer or work done. These restrictive conditions can actually be representative of many physical systems. The Bernoulli’s principle was applied in explaining the design …
