Reliability Measures Improvement and Sensitivity Analysis of a Coal Handling Unit for Thermal Power Plant

The present paper investigates the reliability and sensitivity analysis of a coal handling unit of a thermal power plant using a probabilistic approach. Coal handling unit is the main block of a thermal power plant and it is necessary for a good function of a power plant that its power supply, which is dealt in coal handling unit, must function continuously without any obstacle. The configurati...

Creep Stress Redistribution Analysis of Thick-Walled FGM Spheres

Time-dependent creep stress redistribution analysis of thick-walled FGM spheres subjected to an internal pressure and a uniform temperature field is investigated. The material creep and mechanical properties through the radial graded direction are assumed to obey the simple power-law variation throughout the thickness. Total strains are assumed to be the sum of elastic, thermal and creep strain...

A New Sensitivity Study of Thermal Stress Distribution for a Planar Solid Oxide Fuel Cell

Converting chemical energy into electricity is done by an electro-chemical device known as a fuel cell. Thermal stress is caused at high operating temperature between 700 oC to 1000 oC of SOFC. Thermal stress causes gas escape, structure variability, crack initiation, crack propagation, and cease operation of the SOFC before its lifetime. The aim of this study is to presen...

Creep Strain and Stress Analysis in Laminated Composite Pres-sure Vessels

This study investigates the time-dependent long-term creep strain in a composite cylinder made of glass/vinylester with a unidirectional ply. The cylinder is subjected to an internal pressure and the boundary condition is free–free and acts as thermal insulation. The classical lamination theory (CLT) is used to derive the governing equations as a second-order equation to determine the radial, c...

Creep Analysis of an Isotropic Rotating Disc in the Presence of Thermal Residual Stress

Thermal residual stresses exist within a body in the absence of external loading or thermal gradients. Processing of the composites often involves cooling from higher temperature resulting in thermal residual stresses in the matrix due to restraint imposed by reinforcements. Thermal residual stresses determinately affect the properties of materials thereby shortening their lifetime. These resid...
