Abstract : In this work, we discuss an improved methodology for determining the parameters of rheological functions in
materials with elastic-plastic properties, using the creep process as an example. This approach is based on the theory of
inheritance, where the parameters of the rheological functions are determined by combining graphs (A, α and β) [1, 2].
Traditionally, these graphs are matched through visual alignment of hand-drawn circles, which is prone to significant human
error. The updated methodology presented in this work [6] involves the precise matching of graphs using various computer
programs, and their matching is performed using the least squares approach method. During the research process, we utilized
an existing database of theoretical graphs of rheological functions and values displayed in tabular form [1], which, although
important, contains insufficient information. To expand this database, programs were developed using "Maple," and a
methodology was created for the straightforward calculation of complex mathematical problems with numerical methods, by
transitioning to the complex plane. Based on experimental data from the existing composite material, the improved matching
method was used to calculate correction coefficients that determine the accuracy of the graph matching, and the percentage
differences were estimated.
