Main courses of discovery

  • Development of the scientific foundations of the methodology and principles of studying the structure of materials of different classes based on ideas about the structural sensitivity of acoustic properties in the frequency, time and frequency-time domains
  • Development of new methods of acoustic diagnostics with increased accuracy and informative, which allow identifying the features of the structure and controlling their evolution during the manufacturing and operation process;
  • Research of the complex of physical, mechanical and structural characteristics of materials by resonance and impulse acoustic methods

Theme of scientific research

Non-destructive acoustic methods of research and evaluation of materials and products from them

Best results

  • Theoretical model of the propagation of longitudinal and transverse elastic waves in materials with two-dimensional (crack-like) defects has been developed, which takes into account the dependence of elastic behavior on the stress-strain state of the material, and allows assessing the defectiveness of the material based on the change in the measured acoustic characteristics
  • Computer-oriented program for solving the inverse problem of the theory of elasticity has been developed - calculation of the elastic constants of isotropic and anisotropic materials based on the experimentally determined resonance spectrum of samples
  • Methods for determining elastic moduli of:

           - materials with a structure of cubic symmetry, which is based on measuring the velocities of a longitudinal elastic wave; 
           - materials with defects, which takes into account the dependence of resonance frequencies of sample oscillations on the amplitude, were invented

  • Methods of determining the defectiveness of materials, in particular powder materials, based on the resonance characteristics of samples (parts) were developed (protected by 4 invention patents)
  • Using the developed acoustic methods, the set of characteristics of linear and nonlinear elasticity, as well as the damping ability of porous and compact powder ceramic (Al2O3, Si3N4, HAp), metal (Fe, Ti, Al and its alloys PA-2, AlMg, Al-6Cu-0.4Mn) and composite materials based on them, reinforced with micro- and nanoparticles, were investigated.
  • The universality of revealed nonlinear acoustic phenomena was established, including slow dynamics, distortion of the resonance curve, linear amplitude dependence of the resonance frequency and internal friction, distort ion of the shape of oscillations in the time and frequency-time domains and the related effect of generating the second harmonic in the frequency spectrum of oscillations.
  • It was established that the single-phase compound Ti3Sn exhibits unusual nonlinear behavior; elasticity decreases completely reversibly with deformation, increases both with frequency and with temperature (343 K to 673 K); the damping is extremely high and decreases with frequency, but is independent on strain. The results indicate the presence of a phase transition at about 350 K. The evolution of the structure during the deformation process indicates the activation of the twinning mechanism, which can cause nonlinear elasticity and high energy dissipation.
  • With the use of non-destructive acoustic methods, the following techniques were developed and put into operation:

           - increasing the reliability of control during the manufacture of products from sintered powder materials;
           - determining the defectiveness of the material of main gas pipelines;
           - prediction of the protective properties of combined ceramic-polymer materials according to the criteria of armor resistance and survivability;
           - monitoring the state and predicting the serviceability of the MI-24 helicopter hydraulic steering system element;
           - testing defectiveness of the rollers of the rolling stock after restoring their surface.
