Reliability of Thermal strain and stresses in simple bars

Abstract

In this paper Reliability of Thermal stresses in simples bars whose body may be expand or contract due to some increase or decrease in the temperature of the body were computed. The thermal stresses or strains may also be found out first by finding out amount of deformation due to change in temperature, and then by finding out thermal strain due to the deformation. The thermal stress may be found out the thermal strain .For such thermal stresses in simple bars we are particularly interested in investigating the reliability by using the linear hazard Rate .It is also compared the results between the reliability of thermal stresses in bars if the ends of the bars are fixed to rigid supports and if the supports yield by an amount equal to ∆.it is observed that the reliability is depending on the coefficient of linear expansion ∝.This coefficient of linear expansion is different for each material.
