Paper Abstract

Traditionally used experimental data interpretation methods try to restore real physical fields by the help of mathematical tools. They do not take into consideration physical equations which must be satisfied, field components are being determined independently. Therefore, pure mathematical interpretation is incorrect for creation of a physical field from experimental data. The proposed method is physically based, that means it allows one to find a solution of a combined experimental-theoretical problem. It takes into consideration experimental data, boundary conditions and basic theoretical relationships. One numerical process gives both the searched field and its derivatives. Moreover, that field may be extrapolated to the region where there is no experimental data. The method has been devoted to photoelasticity, moire and strain gauge techniques.
