THE METHOD OF CORRELATION EQUATIONS IN THE EVALUATION OF STRUCTURAL STRENGTH AND RELIABILITY

A great deal of experimental material (cyclic strength of Chromansil steel, growth of fatigue cracks in marine sheet steel, the persistent strength of polymethylmethacrylate) is used to demonstrate the effectiveness of the application of statistical processing on the basis of a compilation of correlation equations, the parameters of which become stable in the case of the selection of more than 20 samples in the selection, which facilitates the determination of prediction reliability.
