For the past week, the Polytechnic University had been the networking center for scientists from all over the world. The 49th International Summer School-Conference Advanced Problems in Mechanics was held on June 21-25 in SPbPU.
“The Advanced Problems in Mechanics (APM) conference takes place at Polytechnic University annually in the last week of June. It connects specialists from different fields of mechanics to interact and then conduct joint research. The work carried out at the Advanced Problems in Mechanics conference makes a significant contribution to the development of mechanics and, consequently, to science as a whole, because mechanics is an integral part of our life and almost all scientific fields,” – Vitaly SERGEEV, vice-rector for Scientific Work at SPbPU, expressed. – “This year’s conference falls under the auspices of the Year of Science and Technology in Russia. June 2021 is the month dedicated to new manufacturing technologies and materials. The development of new materials and technologies is impossible without mechanics.”
This summer, the conference was held in a mixed format: Russian scientists, who were able to attend the APM in person, presented their papers at the Polytechnic University, while foreign scientists joined the conference through video calls. This format allowed for fruitful work, and as a result, the conference was attended by 227 scientists from 19 countries, who presented 180 papers. Scientists joined the meeting from Russian cities, CIS countries, Algeria, Great Britain, Europe, China, New Zealand, the USA, and Turkey. Over 30% of scientists attended the APM in person.
“Despite all the difficulties caused by the coronavirus pandemic, Polytechnic University, together with the Institute for Problems in Mechanical Engineering of the Russian Academy of Sciences, did not stop the well-established tradition of holding an annual conference. What’s more, in 2020, we held it twice: online in June and in a mixed format in November,” – Anton KRIVTSOV, the APM Co-Chairman, Director of the Higher School of Theoretical Mechanics and Gazpromneft-Politech Scientific and Educational Center, said. – “This year, I am happy to welcome scientists from around the world in person and online at the 49th Advanced Problems in Mechanics Conference held at the Polytechnic University.”
The conference was organized by the Peter the Great St. Petersburg Polytechnic University together with the Institute for Problems in Mechanical Engineering of the Russian Academy of Sciences (IPME RAS) with the support of the Russian Academy of Sciences, the Russian National Committee on Theoretical and Applied Mechanics, and Gazprom Neft. Traditionally, the conference organizing committee is based at the Higher School of Theoretical Mechanics, Institute of Applied Mathematics and Mechanics, SPbPU.
The opening event of the Advanced Problems in Mechanics conference took place on June 21 in the Semenov Conference Hall at Technopolis Polytech. During the opening ceremony, the participants were welcomed by Vitaly SERGEEV, vice-rector for scientific work at SPbPU, Vladimir POLYANSKIY, director of Institute of Problems in Mechanical Engineering RAS, Dmitry INDEITSEV, scientific advisor of IPME RAS, academicians Irina GORYACHEVA and Nikita MOROZOV, Professor Wolfgang MÜLLER of the Technical University of Berlin (Germany), Professor Herbert HUPPERT of Cambridge University (UK), Professor Evgeny LOMAKIN of Lomonosov Moscow State University, Maksim FROLOV, Director of the Institute of Applied Mathematics and Mechanics (SPbPU), Anton KRIVTSOV, Director of the Higher School of Theoretical Mechanics. Among the international attendees were Antonio POLITI of the University of Aberdeen (United Kingdom), Abhishek DHAR of the International Center for Theoretical Sciences (India), Francesco DELL’ISOLA of the University of L’Aquila (Italy), Mark KACHANOV of Tufts University (USA), Thierry DAUXOIS of the ENS Lyon (France), and many others.
The APM scientific program included a series of plenary lectures by the world’s leading scientists in mechanics as well as ten scientific sections discussing problems in various areas of mechanics and related fields, such as nano-, micro-, and mesomechanics, quantum mechanics, heat transfer, wave motion, fluid mechanics, and more. This year, the section “Solids and Structures” was the most popular among scientists. So many people wished to take part in this section that it lasted for two days. Among the papers presented here were reports on numerical modeling of curved fractures in space, Popov’s diffraction problem, the cold-spraying composite Cu-W coatings, spinning vibration damping, and others.
The conference also included minisymposia. Typically, the minisymposia focus on more niche and specialized topics from different mechanics areas. This year, seven minisymposia were held on biomechanics, extreme structural loading, abnormal nanoscale energy transfer, nonlinear waves in continuum media, innovative approaches to multiphase gas condensate flow modeling, earthquakes, and seismic protection, and mathematical modeling in petroleum engineering.
Two special events were organized at the 49th Advanced Problems in Mechanics Conference. One of them is the scientific section “Vibration in Science and Technology” dedicated to the memory of Doctor of Physical and Mathematical Sciences Ilya Izrailevich BLEKHMAN. Professor BLEKHMAN, an honorary Russian scientist, outstanding specialist in the field of applied mechanics, and a regular participant of the APM, passed away in February 2021. It is hard to overestimate Ilya Israelievich’s contribution to mechanics, and this scientific section was held to honor his memory and recall his research work.
Another new event was the “Mechanics and Entrepreneurship” section, where Polytechnic University students and graduates who started their successful businesses in the mechanics presented cases and talked about monetizing a scientific idea. In this section, the discussion revolved around two reports: “Photomechanics: a success story. Creating a Manufacturing Technology Company in a Competitive Environment” by SPbPU graduate Alexander LE-ZAKHAROV and “SmartLocker System and Modern Design Thinking Methods” by Nikita GUSIK, a third-year student of the Higher School of Theoretical Mechanics.
The conference also featured a cultural segment. This year a photo exhibition “Flying over St. Petersburg” was opened exclusively for the APM. Authors of photos, Alina KRIVTSOVA and Julia ASATUROVA, Gazpromneft-Politech’s chief specialist on engineering and economic problems, presented the panoramic photos of the North Capital’s most beautiful places from a bird’s-eye view. The photo exhibition authors also created the panoramic images that adorned a new Gazprom auditorium, which opened at the Polytechnic University last month.
The APM-2021 papers will be published as selected publications in APM proceedings: Springer, Lecture Notes in Mechanical Engineering, which is indexed in Scopus and at JUFO level 1, and in Materials physics and mechanics, which is included in the Scopus and Web of Science master list.
The anniversary 50th International Summer School-Conference Advanced Problems in Mechanics takes place next year. This confirms the practical importance of the APM and serves as a precursor to the XIII All-Russian Congress on Fundamental Problems of Theoretical and Applied Mechanics (the leading and most large-scale scientific event in Russia in the field of mechanics). This spring, the Polytechnic University won the competition to host it in 2023. The congress will be held in Saint Petersburg for the first time.
