Abstract

An accurate assessment for fatigue damage as a function of activation and\ndeactivation cycles is vital for the design of many engineering parts. In this\npaper we extend the probabilistic and local approach to this problem proposed\nin [1,2] and [3] to the case of non-constant temperature fields and\nthermomechanical loading. The method has been implemented as a finite element\npostprocessor and applied to an example case of a gas-turbine blade which is\nmade of a conventionally cast nickel base superalloy.\n
