Representatives of the Institute of Physics and Mechanics of Peter the Great St. Petersburg Polytechnic University (SPbPU) and the Advanced Engineering School “Digital Engineering” (AES) took part inXXIV Winter School on Continuous Media Mechanics in Perm. The event was held within the framework of the Program for the creation and development of a world-class scientific center “Supersonic” for 2020-2024 with the support of the Ministry of Science and Higher Education of the Russian Federation.
The event was organized by the Institute of Continuous Media Mechanics of the Ural Branch of the Russian Academy of Sciences – a branch of the Perm Federal Research Center of the Ural Branch of the Russian Academy of Sciences.
The Winter School on Continuous Media Mechanics is held to build a systematic discussion on current issues in this field and is aimed at developing research activities, including among young specialists. The event included a competition of reports among students, postgraduates and young scientists.
The XXIV Winter School on Continuous Media Mechanics was attended by 320 people from 21 cities of Russia, including St. Petersburg, Moscow, Yekaterinburg, Novosibirsk, Izhevsk, Kazan, Samara and others. The event featured 319 reports in eight sections, the abstracts of which were included in the collection of papers on the results of the school.
The main topics of the event program:
computational continuum mechanics, physics and mechanics of meso- and nanostructured systems, mechanics of functional materials, convection, hydrodynamic stability and turbulence, hydrodynamics of non-Newtonian fluids and fluids with special properties, fundamental and applied magnetohydrodynamics, continuum mechanics in biology and medicine, mining mechanics, monitoring of natural and man-made systems.
Scientists, postgraduates, and students of the Institute of Physics and Mechanics of SPbPU presented the results of research and development by research teams on current issues in computational continuum mechanics, mechanics of functional materials, hydrodynamic stability, physics and mechanics of meso- and nanostructured systems, chemomechanics, fundamental and applied hydrodynamics, and gas dynamics. The research results contribute to the development of engineering applications of microelectronics, hydrogen technologies, modern electronic and optoelectronic devices, boiler equipment, methods for testing thermal conductivity at the nanoscale, and calculations of fracture mechanics parameters.

In the course of Olga Antonova’s research, an analysis was conducted of the features of the application of hyperelastic models of materials to describe the behavior of various medical devices and biological tissues used in modern medical practice, primarily in the field of cardiology.
In the future, the obtained results can be used as a basis for modeling the processes of installing coronary and endobiliary stents, prosthetic rings for annuloplasty, optimizing the methods of these medical interventions, as well as in developing recommendations for medical workers, concluded Olga Vladimirovna.
Ekaterina Sadovchenko spoke about the methodology for modeling the process of installing dental implants in bone blocks of different densities using the finite element method.
The research presented by Liliya Nezhinskaya within the framework of the XXIV Winter School on Continuous Media Mechanics will allow the formation of mathematical models of meta-biomaterials of various topologies for their further application in the development of products in the field of tissue engineering for the treatment of bone defects.
It should be noted that the project represents a part research, supported by the Russian Science Foundation, which is carried out by a research group led by the Vice-Rector for Digital Transformation of SPbPU, Head of the SPbPU Digital Engineering School Alexey Borovkov.
Maxim Ivanov spoke about a project to optimize the load-bearing capacity of metal panels with a tetrahedral filler, which is part of his PhD thesis. Layered panels with such a filler are actively used in construction, the automotive industry, and aircraft manufacturing. The results obtained can be used to optimize the technological process of manufacturing a filler of complex shape.
