Comparison of various ways of processing results from hot torsion tests
Original language description
Regular improving the control part, primarily upgrading the control computer, results in the need of solving the issue of fast processing huge amounts of measured data. The most important influence on determining the correct course of flow stress in theused methodology is strain sensitivity index p. In order to define it, it is necessary to refine the course of the measured values of the torque, currently done by a functional filter removing noise. Instead we propose to use approximation using functions that are based on a linear combination of basis functions. That was the reason to test polynomials, Fourier and hyperbolic series with series degree from 7 to 25. The range is so wide because it concerns a heuristic problem with indefinite successfulness of the interlay at the series level. This is also valid for rational functions type Padé and Khoddam. Our statistical verification included 144 tests of three different steels measured within a usual range of temperatures and deformati
