Abstract
Thermoelastic stress analysis (TSA) is a full-field experimental stress analysis technique, see Dulieu-Barton and Stanley [1], which measures the small temperature change developed in a solid under elastic cyclic loading. For linear elastic, homogeneous materials it is assumed that adiabatic conditions prevail and thus the temperature change is directly proportional to the change in the sum of the principal surface stresses (Δ(σ1 + σ2))- However, engineering analysis frequently rely on a knowledge of the individual stress components, which often requires additional methods to separate the stresses.
