Using the perturbation method, we study the processes of nonlinear propagation of the initially harmonic elastic waves in micro-inhomogeneous media, namely, polycrystalline solids with hysteresis-loss saturation and relaxation. The media with the basic hysteresis types, elastic and inelastic, are considered. The efficient nonlinearity parameters of such media are determined for the processes of self-action of a quasiharmonic wave and generation of its higher harmonics.

具有滞后损失饱和和弛豫的多晶固体中的非线性波过程

使用微扰方法,我们研究了初始谐波弹性波在微非均匀介质中的非线性传播过程,即具有滞后损耗饱和和弛豫的多晶固体。考虑了具有基本滞后类型(弹性和非弹性)的介质。这种介质的有效非线性参数是为准谐波的自作用过程及其高次谐波的产生而确定的。
