The results of theoretical numerical-analytical investigation of some kinematic characteristics of the
nonlinear second harmonics for monochromatic axisymmetric normal elastic torsional waves along the axial
direction in transversely isotropic cylinder of circular cross section with a rigid fixed of lateral surface.
Frequency-parametric analysis of amplitude and shape of wave motion into the second harmonic for normal
waves of the investigated type was conducted for the cylinder made from a gadolinium using the proposed
method. The regularities inherent in wave processes of this type are described.
