Abstract
Calculations of transient thermal stress levels were made for composite coatings of hollow cylinders. Stress analysis was done during a thermal cycle of successive heating and cooling periods. Various coating configurations were investigated. The results showed the effect of changes in coating arrangements and the failure modes due to the excessive stress levels. Solutions were obtained by approximate techniques, and a computer program for transient three dimensional thermal stress analysis was developed. The finite element technique was employed for the determination of the temperature distribution and the elastic stress analysis. Fortran IV G Level was used as the programming language.
