The surface of the rail and its weldment is acted by very high repetitive stress through the wheel and because of this contact stress the running surface or subsurface may have cracks or fractures due to fatigue. This work is based on numerical simulation of an aluminum thermite weldment on a UIC 60 rail under multi-axial fatigue crack propagation under the friction with surficial interaction between weldment and wheel with bending load due to vertically applied load through the wheel on the weld. Since contact is highly influenced by vertical load and also for minimizing the simulation time the lateral and longitudinal traction forces are not included in this study. The work formulation and discretization have been done with the finite element method and a non-linear lagrangian algorithm solver is applied. A 3-D rail-weld wheel model assembly and a semi-elliptical crack as a flaw on the weld surface are used to identify 3-Modes of SIFs along with its graphical plot generation. Simulation is performed under multi-axial weld wheel surface contact at different locations on weld running surface, taking into account varying position of fracture crack on weld 3-D model to calculate fracture life of weld joint and observation of fatigue crack propagation. This work involves the numerical and theoretical approach of fracture mechanics on created FE fatigue model using the Linear Elastic Fracture Mechanics (LEFM) method following Paris law for fracture mechanics. All the numerical simulation for critical fracture dimension and cycle count with stress intensity factor for weld failure data is estimated using software ANSYS 2020 academic and plotted, then comparison of predicted and observed transverse crack growth behavior and fatigue life of weld, based on Millions Gross Tonnes (MGT) is discussed.

The basic principle is the Faradays Law of electromagnetic induction. In this device plasma (Ionized gas)is the working fluid similar to the mechanism that happening in the magnetosphere of our earth’s atmosphere. Excepthere the process is controlled and we increase the fluid density and pressure to get maximum efficiency in thegenerating power. Mist problems come from the low conductivity feature in the gas at high temperature. Hightemperature gaseous conductor at high velocity is passed through a powerful magnetic field and a current is generatedand extracted by placing electrodes at suitable position in the gas stream, and hence the thermal energy of gas isdirectly converted in to electrical energy. In this paper the process involved in MHD power generation will bediscussed in detail along with the simplified analysis of MDH system and recent developments in magnetohyd...

It take sales of many tons of steel to obtain enough profit. This amount of tonnage varies of course, with each company's product, processing cost, labor cost, unscheduled down time problems machinery repair cost, and various other business cost.

Prolonging machinery operating duration has the same positive business effect as the sales department selling of many tons of steel.In the steel industry, crane are critical to processing steel. Crane maintenance personnel are finding it is better to work smarter than harder. The largest maintenance expenses incurred for modern, fast and long span electric overhead travelling (EOT crane) is incurred for maintenance activity.

To effective reduce the noise level of a diesel engine the first step is the identification of different engine noise sources. The design and development of modern diesel engines is marked by a reduction in exhaust gas emissions and increase in specific power and torque.Exhaust noise is one of the major contributors to noise from vehicles powered by internal combustion engine. For the same power rating, diesel engines are noisier than gasoline engines, since the combustion characteristics of diesel engines produce more harmonics than slower combustion of gasoline.This paper reviews different noise sources and methods are available for noise reduction of diesel engine.
