In this journal paper an attempt has been made to increase the reliability of engine valve guide using chrome-nickel composites as an alternative material for the engine valve guides. chrome-nickel composites are finding increased application in automobiles, FEA of the chrome-nickel engine valve guide was design and analysis is done by using Ansys13 software. The temperature, thermal stress distribution amd structural analysis of the entire surface of the engine valve guide was analysised. The stress distributions were to be found even throughout the existing materials.

This paper deals with principal strain separation with strain gages. A normal-incidence photoelastic measurement on the PhotoStress coating provides the difference in principal strains at the test point. If the sum of the principal strains can be measured at the same point, then the separate principal strains are obtainable by simply adding and subtracting the two measurements. The measurement is perfprmed on coated specimen.
