The Laboratory of Physical Foundation of Strength was established in 1989. The Head of the Laboratory from 1989 to the present is Doctor of Physical and Mathematical Sciences, Prof. Oleg Borisovich Naimark, The scientific activity of the Lab is directed toward the development of approaches to assessing the reliability and lifetime of advanced materials under wide-range loading conditions by integrating fundamental and theoretical studies into physics and mechanics of deformable solids. The research uses original developments in statistical thermodynamics of media with defects, which made it possible to derive a relationship between the collective behavior of defects and the mechanisms of plasticity and fracture. The studies conducted by the Lab team established an experimental concept for identifying material properties in the framework of the developed models. Symmetric representations of defect ensembles were used to describe effects that arise in condensed media, such as solids and liquids, and in biological meso- and nanosystems.
The Lab research areas include theoretical substantiation and experimental verification of equations of state for condensed matter in a wide range of load intensity (quasi-static, fatigue, dynamic, and shock wave) using high-resolution spatiotemporal recording instruments, as well as investigation of the mechanobiological mechanisms governing living systems. Multiscale analysis that combines high-resolution profilometry, atomic force microscopy, and electron microscopy provides a deeper understanding of how the material structure influences deformation and fracture mechanisms. The Lab researchers designed a hardware and software system for optoacoustic damage stage assessment of composite structures, which is in demand in aircraft engine manufacturing.
The laboratory has completed a number of large-scale international projects and conducts joint research with the United Engine Corporation, Rosatom State Corporation, and Roscosmos State Corporation. Specifically, the laboratory staff, together with the Shvabe holding company (JSC PO UOMZ, Yekaterinburg), is participating in the Roscosmos State Corporation's targeted project "Interference and Fluorometric Studies of Biological Objects Using the MIM-MKS Multifunctional Hardware Complex in Microgravity Conditions" to develop a methodology for medical monitoring using laser microscopy during long-duration spaceflight.
