Abstract

In this work thermoelastic stress analysis (TSA) is used to reveal information about the damage evolution process in small stainless steel pipework. TSA is a well-established stress analysis technique, see Dulieu-Barton and Stanley [1], based on the measurement of the small temperature change developed in a material as a result of elastic cyclic loading. The temperature change is directly proportional to the change in the sum of the principal surface stresses (Δ(σ1 + σ2)), see Stanley and Chan [2]. This relationship is usually sufficient for linear elastic, homogeneous problems, where the assumption is made that the temperature change is adiabatic.
