    Professor Wieslaw Ostachowicz was graduated from Gdansk University of Technology, Poland (receiving BSc and MSc degree in Mechanical Engineering). He defended PhD at Gdansk University of Technology, Poland (in Mechanical Engineering), and defended DSc (habilitation, 1980) at Gdansk University of Technology, Poland (in Mechanical Engineering). In 1989 the President of Poland nominated him to the Professor position (Professor Title). Earlier he was recommended to this position by the Institute of Fluid Flow Machinery, Polish Academy of Sciences (IMP PAN).

    He is the Corresponding Member of Polish Academy of Sciences (elected on December 1, 2016).

    Prof W. Ostachowicz was employed in several institutions: (1) in the IMP PAN, Gdansk (1970–1972) as an assistant; (2) in Navy Shipbuilding Yard, Gdynia (1972–1973) as a designer; (3) at Gdansk University of Technology, Department of Mechanical Engineering (1973–1987) as senior assistant, assistant and associate professor; (4) in the IMP PAN (1986–present) as an associate professor and professor (from 1989); (5) in Gdynia Maritime University (2004–2012) as an associate professor and (6) at Warsaw University of Technology (2013–2017) as an associate professor.

    The list of his temporary positions opens: chairman of the Department of Mechanics and Strength of Materials at Gdansk University of Technology (1982–1987), the deputy director for scientific affairs at the IMP PAN (1986–1992); head of the Centre for Mechanics and Machines (from 1998– present), at the IMP PAN; and a chairman of the Department of Mechanics of Intelligent Structures (from 1996– present) at the IMP PAN. He was also employed as an expert of UNIDO (United Nations Industrial Development Organization) at the Instituto de Investigaciones Electricas, Cuernavaca, Morelos, Mexico (1987 and 1990). He was Visiting Professor at: (1) the Syracuse University, the Department of Mechanical Engineering, USA (1980–1981); (2) the University of Glasgow, the Department of Mechanical Engineering, UK (2000–2003); (3) the University of Northampton, the School of Science and Technology, UK (2014–2016); (4) Ecole Nationale Supérieure d’Arts et Métiers (ENSAM), Paris, France (2017).

    Prof W. Ostachowicz has led dynamics research at the IMP PAN throughout last twenty eight years. Personally, he specializes in several important sub–disciplines, like structural health monitoring techniques, vibration control, structural dynamics, composite structures, multifunctional materials, smart materials and structures, damage assessment of structures, working in these fields both theoretically and experimentally. In the past twelve years, his research was focused on the development and use of the Spectral Finite Element Method for damage assessment as well as smart materials applications. The aim of his research in guided wave propagation has been to develop a number of vibro–acoustic–ultrasonic methods for damage detection using smart sensor technologies. Those methods have demonstrated effectiveness and sensitivity to small cracks in metallic and composite structures, without restrictions on load, boundaries or temperature conditions.

    Professor W. Ostachowicz published 283 archival international journal papers, 332 refereed international conference papers and over 200 technical reports, predominantly in the damage detection, structural health monitoring and advanced signal processing areas. Also, he published over 45 papers (in the English language) in Polish Journals. Prof W. Ostachowicz published 5 monographs, 7 book chapters, 4 proceedings volume in the fields of structural dynamics and SHM. These have been published by worldwide famous publishers as Springer, Wiley, Kluwer, World Scientific, CRC Press, etc. The 283 papers currently represented on JCR Web of Science are uniformly distributed in the highest–quality international journals and have attracted 2550 citations (without self–citations). One of his paper published in the Journal of Sound and Vibration (Analysis of the effect of cracks on the natural frequencies of a cantilever beam, Vol. 150, 2, 191–201, 1991) has been cited 318 times. His second most highly–cited paper was published in Journal of Sound and Vibration (Wave propagation modelling in 1D structures using spectral finite elements, Vol. 300, 1–2, 88–100, 2007) is attracted by 94 citations. His third most highly–cited paper was published in Journal of Sound and Vibration (The dynamic analysis of a cracked Timoshenko beam by the spectral element method, Vol. 264, 5, 1139–1153, 2003) has been cited 87 times.

Struktura Ośrodka

W Ośrodku Mechaniki Maszyn funkcjonują obecnie trzy zakłady:

Prowadzi badania w dziedzinie dynamiki maszyn, w szczególności cieplnych maszyn przepływowych. Do modelowania rzeczywistych obiektów stosuje modele opracowane na podstawie metody elementów skończonych. Badania koncentrują się wokół zagadnień drgań, wytrzymałości i żywotności elementów konstrukcji turbin parowych (łopatki, tarcze wirnikowe, korpusy). Modele opracowano z uwzględnieniem rzeczywistych warunków pracy obiektów. Zakład opracował oryginalne modele uszkodzonych elementów maszyn (np. z pęknięciami zmęczeniowymi). Ponadto w Zakładzie prowadzone są badania w dziedzinie statyki i dynamiki konstrukcji kompozytowych. Prace te dotyczą kompozytów o sterowalnych własnościach mechanicznych (w których stosowane są elementy wzmacniające z pamięcią kształtu). Prowadzi się także badania dynamiki konstrukcji kompozytowych z typowymi uszkodzeniami (pęknięcia, delaminacje, rozwarstwianie).

Tematyka badawcza Zakładu koncentruje się także wokół zagadnień nieliniowej teorii i analizy numerycznej konstrukcji powłokowych, w tym powłok nieregularnych z defektami materiałowymi. Ponadto prowadzi się badania dynamiki (drgania swobodne, wymuszone i samowzbudne), wytrzymałości układów łopatkowych i wirników turbin parowych z uwzględnieniem warunków eksploatacyjnych. Ostatnim nurtem badań jest modelowanie wieloskalowe i geometryczne ciał stałych z mikrostrukturą, w tym między innymi zagadnienia przemiany martenzytycznej, pękania, tarcia, zużycia i zniszczenia.

Zakład prowadzi działalność naukową z zakresu modelowania oddziaływań dynamicznych zachodzących w podukładach typu: linia wirników- łożyska ślizgowe-podpory-fundament. Opracowane zostały przestrzenne modele wymiany ciepła w węzłach łożyskowych oraz nieliniowe metody opisu drgań takiego układu. Opis nieliniowy umożliwia zastosowanie opracowanych narzędzi do celów związanych z diagnostyką według modelu dużych obiektów energetycznych. Modelowane są defekty w pracy przyjętych obiektów a następnie budowane są relacje typu defekt-symptom. Zakład prowadzi również w szerokim zakresie prace o charakterze utylitarnym na rzecz przemysłu (rozbudowa baz wiedzy systemów eksperckich, obliczenia charakterystyk łożysk antywibracyjnych, analiza stanu dynamicznego różnego rodzaju maszyn wirnikowych).
