Abstract

Eigenstresses and eigenstrains act out a very important role in many branch- es of applied mechanics. The eigenparameters may represent plastic strains or plastic stresses (or also prestresses, change of temperature etc.), and may also serve as free parameters for improving numerical models to get the computed quantities that should be as close as possible to the real state. In order to get a reasonable agreement between these quantities when compar- ing both computed and measured values, a special variational formulation can be stated, dealing with the minimum variance of differences between measured and computed values. When using a very useful treatment, trans- formation field analysis (TFA), having recently been proposed by Dvorak and improved by Dvorak & Prochazka^, the
