“…Ono (2020) and Golyandin et al (1998) conducted their forced-oscillation experiments at zero bias stress on annealed polycrystalline aluminum and annealed stainless steel, respectively, such that the initial dislocation densities in their samples were lower than in our own measurements. Therefore, it is not surprising that our attenuation measurements of aluminum and stainless steel are higher than those of Ono (2020) and Golyandin et al (1998). However, the Q -1 of acrylic exhibits a reasonable agreement with the measurement from Fukada (1954) since dislocations are not responsible for damping in this material.…”

We describe a high-temperature, uniaxial creep apparatus designed to investigate nonlinear attenuation of materials over a wide range of temperatures (25-1300°C) using forced oscillations combined with a bias stress. This apparatus is primarily designed for investigation of minerals and rocks with high melting temperatures. An oscillatory compressional stress is used to determine attenuation and Young's modulus at frequencies of 10 -2 to 10 2 Hz and high stress amplitudes (>0.1 MPa). Large bias stresses are applied in addition to the oscillatory stresses such that attenuation tests are conducted simultaneously with ongoing creep.The complex compliance of the apparatus was characterized by conducting calibration tests on orientated crystals of sapphire. The real part of the apparatus compliance exhibits a dependence on sample length and frequency, whereas the imaginary part is only dependent on frequency.The complex compliance is not dependent on the oscillation amplitude or the bias stress. We assess the accuracy and precision of this calibration by comparing measurements of the attenuation and Young's modulus of stainless steel, aluminum, and acrylic to previously published values. We outline a set of criteria defining the conditions over which this apparatus can accurately determine the attenuation and Young's modulus of a sample based on the sample length and expected values of attenuation and Young's modulus.

“…aluminum [14,15], indium [16,17], zinc [18], lead [19]) increases, saturation of hysteresis DD and EMD occurs. (Generally speaking, hysteresis behavior is characteristic not only of the mechanical properties of polycrystals, but also of the magnetic and dielectric properties of ferromagnets and ferroelectrics, with saturation effects [20,21] also occurring for them.…”

Theoretical and numerical studies of nonlinear acoustic effects arising from the propagation of initially harmonic waves in polycrystalline solids with saturation of amplitude-dependent internal friction have been carried out. Two main types of hysteresis are considered: elastic and inelastic. A comparative analysis of the regularities of nonlinear effects is carried out and the characteristics of nonlinear quasi-harmonic waves in such media are determined: amplitude-dependent losses and changes in propagation velocity, as well as amplitudes of higher harmonics. A method for determining the type of polycrystal hysteresis based on the analysis of theoretical and experimentally established amplitude dependences of nonlinear effects is proposed. Keywords: elastic waves, amplitude-dependent internal friction.
