The authors have attempted to develop an analytical method to estimate the variability of life evaluation in a structure under thermal load by treating the variations in the heat transfer boundary conditions around the structure using the stochastic finite-element method. This article describes the formulation of the variability of solution used in the analytical method, and then shows the results of benchmark analysis with the general purpose FEM code "MARC" to confirm the accuracy of the analytical method. The variability of life evaluation is also shown as an example in order to demonstrate the validity of this method.
