| Abstract: | The results of experimental studies of the energy scattering by soft, viscoelastic materials with certain combinations of a planar stress distribution, established by the superposition of a cyclic shear on tension-compression, are given. Special graphs were used for evaluating the damping properties of the materials, i.e., lines of equal damping, which enabled the equivalent uniaxial stress to be found for each combination of planar stress distribution, which produced the same specific scattering of energy. It is shown that the use of the superposition principle for calculating the mechanical losses in a planar stress distribution from experimental data obtained in uniaxial cyclic loading leads to large errors.Volgogradskii Polytechnic Institute.
