The aim of this paper is to present a method to be used for analysis of stress-strain loops under variable amplitude loading. The method for determination of plastic strain energy parameter ΔWpl consists in determination of envelopes around stress-strain branches (increasing and decreasing) formed in effect of application of a loading program. The method involves development of envelopes to determine energy parameter from the highest (for the highest loading cycle) to the lowest (for the lowest cycle). The paper includes results of stress-strain loop for steel C45.
