Abstract
Experimental data obtained by monitoring temperature variations due to the thermoelastic effect during cyclic loading are related only to the sum of the principal stresses (referred to as bulk stress). This paper presents a method for obtaining the individual stress components from this bulk stress data in a three-dimensional case using a finite element model. The particular case of a beam rigidly constrained at one end and loaded by unknown applied pressures and shears at the other end is studied in detail. It is shown that the problem is solvable if the cross-section is square, but not solvable if the cross-section is circular.
