  • Pozycja
    On a stability of thin microperiodic plates
    (Wydawnictwo Politechniki Łódzkiej, 1997) Jędrysiak, Jarosław
    The structural macromechanics is applied to investigate the stability of a composite plate. Thin elastic plates with microperiodic structure in planes parallel to the midplane are examined. A new retined approach is used to the problem of the dynamic stability of periodic plates. Some special results are shown
  • Pozycja
    On the modelling of vibrations of functionally graded plates
    (Wydawnictwo Politechniki Łódzkiej, 2012) Kaźmierczak-Sobińska, Magda; Jędrysiak, Jarosław
    In this paper there are considered functionally graded plates. To describe vibrations of these plates and take into account the effect of the microstructure it is applied the tolerance method, cf. [10, 11]. There are formulated governing equations of three presented models: the tolerance model, the asymptotic model and the combined asymptotic-tolerance model.
  • Pozycja
    On a certain nonlinear model of thin periodic plates
    (Wydawnictwo Politechniki Łódzkiej, 2012) Domagalski, Łukasz; Gajdzicki, Michał; Jędrysiak, Jarosław
    The object under consideration are thin plates, which structure is periodic in planes parallel to the midplane. Plates of this kind consist of many small, repetitive elements, called periodicity cells, that can be treated as thin plates. The microstructure size is characterized by the diameter of the cell, which is called the microstructure parameter l. It is assumed that mechanical properties (bending and membrane stiffness tensors' components) of such plates are periodic, highly-oscillating, non-continuous functions. The main aim is to propose a mathematical model describing moderately large static deflections problem of considered plates, which is based on the tolerance modelling technique. A calculational example for a specific problem is included. The results are compared with results obtained within the linear model and with Finite Element Method.
