Determining Stress Components from Thermoelastic Data: A Theoretical Study

Abstract

This paper presents a method for decomposing bulk stress data into individual stress components. This has applications in the field of thermoelastic stress analysis where the raw data are related only to the sum of the principal stresses (referred to as bulk stress). By considering equilibrium, and with some knowledge of the form of the solution and boundary conditions, it is shown that bulk stress data for a two dimensional body may be separated into stress components by mean of a least squares method. Keywords: Stress analysis, Thermoelasticity, Spate, Inverse problems, Australia.
