Abstract
We propose a parameter state of stress as the sum of the principal stresses relative to the odds of their influence. Influence coefficients are mechanically-mi material properties. Plasticity chart with this indicator is proposed to approximate the exponential function. Checking for different materials showed sufficient proximity of the experimental points to a diagram of plasticity. Recommendations are given for determining the coefficients of arbitrary types of tests. The minimum number of tests - 4.
