Abstract

The construction of digital thermo-elastic images of isopachics builds the ground for hybrid numerical - experimental thermo-elastic analysis and enables to analyse the experimental results with greater precision. The calculation of the precise field of the values of s x+s y from the displacement finite element formulation requires the application of the proposed procedure of conjugate approximation with smoothing for this specific problem. This smoothing procedure enables the generation of thermo-elastic images of isopachics on rather coarse conventional finite element meshes.
