The third order elastic moduli are fundamental parameters of elasticity characterizing the intrinsic nonlinear properties of solids. Their precise values are very necessary for description of nonlinear processes in materials. However, up to now many of the methods of determination of the 3d order moduli lead to reliable results mostly for crystalline solids. For isotropic materials these moduli are known with very low accuracy, that results in a necessity of new methods of their determination. We propose a new approach to determine the 3d order elastic moduli of non-crystalline materials by means of measurements of bulk strain solitary wave parameters.
