Заслуженный деятель науки и техники РСФСР Евгений Леопольдович Николаи (1880-1950) работал на кафедре с 1903 года, а в периоды с 1930 по 1936 и с 1944 по 1950 был ее заведующим. В 1916 г. Е.Л.Николаи успешно защитил магистерскую диссертацию “К задаче об упругой линии двоякой кривизны”, а в июне 1917 г. Ученый Совет Петроградского политехнического института единогласно избрал его на должность профессора по кафедре теоретической механики. Проф. Е.Л.Николаи читает цикл лекций по общему курсу теоретической механики на факультетах: механическом, химическом, индустриального земледелия и по некоторым специальным курсам – теории упругости, гидродинамике, динамике машин. В процессе накопленного педагогического опыта Е.Л.Николаи приходит к убеждению о необходимости иного построения курса лекций по теоретической механике и создает собственный курс механики для тех втузов города, где он преподавал (Политехнический, Технологический, Путей сообщения). Затем Евгений Леопольдович составляет фундаментальное руководство в двух частях “Лекции по теоретической механике” (1922-1925). Этот учебник вскоре был принят во всех втузах нашей страны и тем самым составил целую эпоху в преподавании теоретической механики: до 1937 года первая часть учебника выдержала одиннадцать, а вторая пять повторных изданий. В последующие годы Е.Л.Николаи выпустил третью часть, в которую включил уравнения Лагранжа, и теорию малых колебаний, и в 1939 г. в переработанном и значительно дополненном виде учебник вышел в трех частях под названием “Теоретическая механика”. Написанный с предельной ясностью и четкостью, этот курс дает необходимые каждому инженеру знания по теоретической механике и содержит многочисленные технические иллюстрации законов механики.

Yevgeny Leopoldovich Nicolai, the honored worker of science and technology of the RSFSR (1880-1950) worked at the department since 1903. He headed the department from 1930 to 1936 and from 1944 to 1950. In 1916, Nicolai successfully defended his master’s thesis “On the problem of an elastic line with the double curvature”. After that, in June 1917, he was unanimously elected by Academic Senate of Petrograd Polytechnic University (presently named SPbSPU) as a professor at Department of Theoretical Mechanics.
 +
Professor Nicolai delivered lectures on theoretical mechanics and special courses on theory of elasticity, fluid mechanics, and machine dynamics at the Mechanical, Chemical and Industrial-Agricultural departments.
 +
While working as a lecturer Professor Nicolai concluded that existing course “Theoretical Mechanics” should be revised. He developed new lecture courses for the departments where he worked (Polytechnic University, Technologic University, University of Railway Engineering).
 +
On the base of the courses he compiled a fundamental textbook in two parts “Lectures on Theoretical Mechanics” (1922-1925). Soon this textbook became renowned in all the Russian technical universities and it opened a new era of teaching Mechanics. Until 1937 the first part of the textbook was reprinted for 11 times, and second for 5 times.  In the next years Nicolai published the third part, which included Euler-Lagrange equation and theory of small-amplitude oscillations. Finally, in 1939, the three parts of revised and updated textbook entitled “Theoretical Mechanics” was announced. Written with clarity and precision, this course provides the necessary knowledge to every engineer in theoretical mechanics and contains numerous illustrations of the laws of Mechanics.

В разносторонней научной деятельности Е.Л.Николаи достаточно отчетливо прослеживается история становления и развития четырех направлений исследований: 1) теория упругости, главным образом, теория деформации тонких стержней и теория устойчивости стержней; 2) теория вибраций; 3) теория гироскопов и гироскопических приборов; 4) история механики. В 1928г. Е.Л. Николаи прочел свой, ставший чрезвычайно знаменитым, доклад на тему “Об устойчивости прямолинейной формы равновесия скрученного стержня”. Этой и рядом других работ Е.Л.Николаи утвердил себя признанным основоположником нового научного направления - теории устойчивости упругих неконсервативных систем. Е.Л.Николаи активно участвовал в становлении новой области промышленности – гироскопического приборостроения. Наряду с научной и педагогической деятельностью проф. Е.Л.Николаи много времени уделял организационной работе: проректор по учебным делам (1920-1921), декан инженерно-строительного факультета (1921-1923), декан физико-механического факультета (1930, 1937-1938). В Физико-механическом институте (1930-1934) он заведует отделением технической механики и открывает специализацию “Динамические явления в машинах и механизмах”, что в настоящее время соответствует специальности “Динамика и прочность машин” (кафедра “Механики и процессов управления”, ФМФ). Евгений Леопольдович был инициатором создания в нашей стране специального журнала “Механика и прикладная математика”; был ответственным редактором “Вестника механики и прикладной математики” Ленинградского механического общества; в 1933 году он стал всесоюзным журналом “Прикладная математика и механика”, а Е.Л.Николаи был его ответственным редактором до 1936 г.

Anatoly Isaakovich Lurie, corresponding member of the USSR Academy of Sciences (1901-1980) headed the department from 1936 to 1944. He is the author (with L.G. Loitsiansky) of the widely known ”Theoretical Mechanics” textbook (1932), the latest edition of which was published in 1986. In this textbook, the classical mechanics was explicated using the vector analysis for the first time in Russia. Numerous tasks, which had not only illustrative, but also practical significance, was an important part of the textbook. Lurie is the author of eight books, including the fundamental monographs of an encyclopedic character: ”Analytical Mechanics” (1961), ”Theory of elasticity” (1970), ”Non-linear theory of elasticity” (1980). One can read more about Lurie’s miscellaneous scientific research in his ‘memoirs’ on “Mechanics and control processes” department, which he headed from 1944 to 1976.

Georgy Nikolaevich Nikolsky[edit]

Professor Georgy Nikolaevich Nikolsky headed the department from 1950 to 1954. He was a prominent expert in the field of automatic control processes and one of the authors of the first in the USSR unmanned aircraft system.

Nikolai Nikolaevich Polyakhov[edit]

Professor Nikolai Polyakhov (1906-1987), honored Worker of Science and Technology of the RSFSR, headed the department from 1954 to 1955. He is the author of the well-known works on fluid mechanics and ”Theoretical Mechanics” textbook for the universities (in collaboration with S.A. Zegzhda and M.P. Yushkov).

Georgy lustinovich Janelidze[edit]

Professor Georgy lustinovich Janelidze (1916-1964) headed the department from 1955 to 1964. His textbook ”Theoretical Mechanics in examples and problems”, written in collaboration with the department members M.I. Bat’ and A.S. Kelzon, became popular among Russian students. G.I. Janelidze was a dean of the Faculty of Physics and Mechanics from 1956 to 1964. He is an author of the well-known works on the general mechanics, mathematics, physics, medicine, theory of elasticity and plasticity, theory of naturally twisted rods. He wrote such monographs as, for example, “Statics of thin-walled rods” (1948, published in collaboration with Ya.G. Panovko) and “Vibratory displacement” (1964, with I.I.Blekhman). In his last monograph he had discovered new effects adopting the methods of the nonlinear theory of oscillations. The discovery has made possible the effective granular media transport. The transport process is carried out through an excitation of particles’ transverse oscillations.

Vadim Konstantinovich Prokopov[edit]

Professor Pavel Andreevich Zhilin (1942-2005) was the head of the department from 1989 to 2005. He was the member of Russian National Theoretical and Applied Mechanics Committee, the member of Presidium of the “Applied Mechanics” Research and Methodology Committee and member of the Research and Methodology Committee on Theoretical Mechanics under the Ministry of General and Professional Education of Russia. P.A.Zhilin was an academician of Saint-Petersburg Academy of Science on Strength Problems (SPAS). He published more than 150 scientific and methodological works. One of his main research directions was the extension of the methods of Rational Mechanics to non-mechanical fields such as Micro-physics and Electrodynamics.

His main results are the following: development of the general theory of the elastic shells, without using static and kinematic hypothesis; general formulation of the fundamental laws of dynamics, applicable in the non-mechanical fields; development of the group theory for non-Euclidean tensors; introduction of a new solid body oscillator necessary for the multi-polar media development; establishing a theorem on the representation of the rotation groups, engaging the known findings on the subject; development of the modified electrodynamics equations describing not only transversal, but also longitudinal waves; derivation of the dynamic equations for the Kelvin media. This equation gives a strict mechanical interpretation of the Schrödinger and Klein-Gordon equations.

Anton Miroslavovich Krivtsov[edit]

Professor Anton Miroslavovich Krivtsov is the head of the department since 2005. He is the member of Russian National Theoretical and Applied Mechanics Committee and the head of “Laboratory for Discrete Models in Mechanics” IPME RAS since 2012. A.M. Krivtsov is also a scientific supervisor of Center for scientific and technical creativity of the youth (SCY) SPbPU. A.M. Krivtsov was made a professor of RAS in 2015. His research interests lay in the different fields of Mechanics, Physics and mathematical modeling: dynamics of the rigid body; continuum mechanics; theory of the microstructured media; nanomechanics; theory of vibration processing of materials; astrophysics. The main direction of A.M. Krivtsov’s science work is the mathematical and computational modeling of the microstructured media based on the molecular dynamics and the particle dynamics methods.

A.M. Kivtsov contributed to the development of the particle dynamics method. His contribution allowed to discover new effects that were difficult to describe by the means of continuum mechanics because of the discontinuities, arising in the case of large non-elastic deformation and fracture. The particle dynamics method allows to investigate such processes with regard to the internal structure of the media or model a system at the micro- or nanoscale level.
