Abstract
High temperature components such as cooled or uncooled first stage turbine blades are subjected to triaxial stress fields, mainly induced by constrained thermal strain fields during service. The steepest temperature gradients and consequently the largest thermoinduced stresses are generated during start-up and shut-down phases of turbine operation.
