Abstract

The results of calculating the adjustment factor for the geometric dispersion of sound velocity \(\beta \) in compact products of square cross section for various ratios of thickness to the side of cross section are presented. Using simulation in the ANSYS software environment, it has been shown that as the ratio increases, the main vibration mode transforms, causing the emergence of intrinsic resonance in the compact product. The transformation is from longitudinal waves in compact products of the “pile” type to Lamb waves in compact products of the “plate” type. At the same time, a nonlinear change in the coefficient \(\beta \) occurs in compact products that makes it possible to make a correction for the effect of geometric dispersion. The dispersion dependence of the coefficient \(\beta \) on the ratio of the thickness to the side of the product section has been calculated in compact square cross-section objects.
