Laboratory of Thermomechanics of solids, Institute of continuous media mechanics, Urals branch of RAS was created on 17 June 2018 on the basis of the laboratory of Physical foundations of strength the head of which to this day is a respected scientist, doctor of physico-mathematical Sciences, Professor Oleg Borisovich Naimark. The initiator of the creation and ideological inspirer of the new laboratory was the closest student naymark O. B. Professor of RAS, doctor of physical and mathematical Sciences, Deputy Director of IMSS UB RAS for scientific work Oleg A. Plekhov. The basis of the new laboratory team were his colleagues, students and graduate students.

 A distinctive feature of the new laboratory is the Association of specialists-theorists, specialists-calculators and experimenters, which allows to solve both fundamental problems in various fields of science and specific applications.

    The main directions of applied research carried out within the framework of R & d contracts are:

  • mechanical tests of metals, alloys, composite materials, elastomers, rocks, as well as assemblies and structurally similar elements under various types of loading (quasi-static, low -, multi-and gigocyclic fatigue) and temperatures (from -50 to 230 0C);
  • multiphysical numerical simulation of heat transfer processes with phase transitions, filtration, mechanical behavior and destruction of materials, structural elements, assemblies and assemblies, media and mountain ranges;
  • non-destructive testing (including automated) of objects from micro - to macro-sizes using the methods of infrared thermography, acoustic emission, x-ray tomography, digital image correlation, the method of potential drop;
  • the solution of problems of optimization of geometrical parameters, parameters of technological processes on the basis of multiphysical model of initial object.

    The main directions of fundamental research of the laboratory of Thermomechanics of solids are:

  • thermodynamics of fatigue crack propagation in metals and alloys;

  • thermodynamics of inelastic deformation of metals and alloys;

  • thermodynamics of phase transformations in fluid-saturated rocks, soils and media;

  • mechanisms and regularities of damage development in natural and artificial materials and media;

  • defining relations of deformation and fracture of materials and media with defects;

  • mechanisms and regularities of the influence of weak physical fields on the processes of deformation and destruction of materials and media;

  • early harbingers of the destruction of the materials and environments for various configurations of external loads with the use of different NDT methods.
