  • Jaroniek, Mieczysław; Niezgodziński, Tadeusz (Lodz University of Technology. Faculty of Mechanical Engineering. Department Division of Dynamics.Wydawnictwo Politechniki Łódzkiej. Wydział Mechaniczny. Katedra Dynamiki Maszyn., 2015)
    Manufactured by the end of the 80s in the last century steel structures were made of steel which contain signi cant amounts of non-metallic inclusions. As a result of many years of intensive use of the structures made ...
  • Just, Paweł; Pisarek, Bogusław (2014)
    Small additions of Cr, Mo and W to aluminium-iron-nickel bronze are mostly located in phases κi (i=II; III; IV),and next in phase α (in the matrix) and phase γ2. They raise the temperature of the phase transformations in ...
  • Urbaniak, M.; Świniarski, J.; Niezgodziński, T. (Wydział Mechaniczny. Katedra Wytrzymałości Materiałów i Konstrukcji. Politechnika ŁódzkaLodz University of Technology. Faculty of Mechanical Engineering. Department of Strength of Materials and Structures, 2015)
  • Manevich, A.; Kołakowski, Zbigniew (Polskie Towarzystwo Mechaniki Teoretycznej i Stosowanej, 2011)
    Dynamics of Timoshenko's beam made of a viscoelastic material is studied. Dimensionless equations of motion are obtained, depending only on two parameters, one of which relates to the shear flexibility and the second – to ...
  • Woźniak, Czesław; Wągrowska, M.; Szlachetka, O.; Witkowska-Dobrev, J. (2012)
    The object of analysis is an unbounded layer made of two isotropic, linear elastic materials and periodically laminated along the Ox1 axis (cf. Fig.1). The layer is resting on the rigid base. It is ...
  • Pisarek, Bogusław (2014)
    With the increase in wall thickness of the casting of iron-nickel-aluminium-bronze, by the reduction of the cooling rate the size of κII phase precipitates increases. This process, in the case of complex aluminium bronzes ...
  • Wójcik, Ryszard; Wejman, Przemysław (Lodz University of Technology. Faculty of Mechanical Engineering. Department Division of Dynamics.Wydawnictwo Politechniki Łódzkiej. Wydział Mechaniczny. Katedra Dynamiki Maszyn., 2016)
    The paper presents a study of the process of grinding titanium grinding wheels with mikrokorundu, sanding at surfaces involving liquid - cooling lubricants using MQL, used machining fluid - propylene glycol and other ...
  • Lefik, Marek (Polskie Towarzystwo Mechaniki Teoretycznej i Stosowanej, 2004)
    An application of Artificial Neural Networks for a definition of the effective constitutive law for a composite is described in the paper. First, a classical homogenisation procedure is directly interpreted with a use of ...
  • Świerczyński, Jakub (Stowarzyszenie Inżynierów i Techników Mechaników Polskich, 2012)
  • Awrejcewicz, Jan; Olejnik, Paweł (Politechnika Łódzka. Wydział Mechaniczny. Katedra Automatyki, Biomechaniki i Mechatroniki., 2015)
    A pendulum in form of an equal arms angle body being a part of a two degrees-of-freedom mechanical system with friction is identified with respect to the observed in uence of some resistance of its rotational motion ...
  • Kotełko, M.; Mołdawa, A. (Wydział Mechaniczny. Katedra Wytrzymałości Materiałów i Konstrukcji. Politechnika ŁódzkaLodz University of Technology. Faculty of Mechanical Engineering. Department of Strength of Materials and Structures, 2015)
  • Pijanowski, Karol; Dąbrowski, Artur; Balcerzak, Marek (Lodz University of Technology. Faculty of Mechanical Engineering. Department Division of Dynamics.Wydawnictwo Politechniki Łódzkiej. Wydział Mechaniczny. Katedra Dynamiki Maszyn., 2015)
    The main purpose of this text is to present application of the Largest Lyapunov Exponent (LLE) as a criterion for optimization of the new type of simple controller parameters. Investigated controller is the part of numerically ...
  • Mróz, Andrzej (Wydawnictwo Politechniki Łódzkiej. Wydział Mechaniczny. Katedra Dynamiki Maszyn., 2012)
    This paper presents the results of numerical analysis of the aluminium profiles subjected to dynamic, of different time duration impulse loading. The analysis includes the change in cross–section of the roof rail, ranging ...
  • Świniarski, Jacek; Kowal-Michalska, Katarzyna; Niezgodziński, Tadeusz (2012)
  • Łagodziński, Jakub; Miazga, Kacper (Politechnika Łódzka. Wydział Mechaniczny. Katedra Automatyki, Biomechaniki i Mechatroniki., 2015)
    Air-foil technology is an interesting alternative for classic rolling or oil bearings in turbomachinery. It ensures low power losses, do not require external lubrication or pressurization and is capable of working with ...
  • Nowak, Andrzej; Nowak, Paweł; Awrejcewicz, Jan (Politechnika Łódzka. Wydział Mechaniczny. Katedra Automatyki, Biomechaniki i Mechatroniki., 2015)
    The paper presents experimentally verified computational model of the collecting electrodes in electrostatic precipitator (ESP). Discretisation of the whole system, both the beams and the electrodes, is carried out by means ...
  • Kubiak, Tomasz (Polskie Towarzystwo Mechaniki Teoretycznej i Stosowanej, 2006)
    An analysis of local buckling of thin-walled beam-columns, taking account global precritical bending within the first order approximation, is presented in the paper. The problem of interactive buckling of the structure is ...
  • Kołakowski, Z.; Teter, A. (Wydział Mechaniczny. Katedra Wytrzymałości Materiałów i Konstrukcji. Politechnika ŁódzkaLodz University of Technology. Faculty of Mechanical Engineering. Department of Strength of Materials and Structures, 2015)
  • Andrianov, Igor V.; Awrejcewicz, Jan; Danishevskyy, Vladyslav V.; Markert, Bernd (Politechnika Łódzka. Wydział Mechaniczny. Katedra Automatyki, Biomechaniki i Mechatroniki., 2015)
    Nonlinear longitudinal vibrations of a periodically heterogeneous rod are considered. Geometrical nonlinearity is described by the Cauchy–Green strain tensor. Physical nonlinearity is modelled expressing the energy of ...
