    Stability of thin uniperiodic cylindrical shells
    (Katedra Wytrzymałości Materiałów i Konstrukcji, Politechnika Łódzka, 2003) Tomczyk, B.
    The aim of this contribution is to propose a new averaged model for stability analysis of thin linear-elastic cylindrical shells having the periodic structure along one direction tangent to the shell midsurface. In contrast with the known homogenized models the proposed one makes it possible to describe the effect of the periodicity cell size on the overall shell behavior ( a length-scale effect ). In order to derive the goveming equations with constant or slowly varying coefficients the known tolerance averaging procedurc is applied. The comparison between the proposed model and the model without the length-scale effect is presented.

    Stability of composite plates under varying axial forces
    (Katedra Wytrzymałości Materiałów i Konstrukcji, Politechnika Łódzka, 2003) Konieczny, S.; Langier, Sz.; Mes, R.
    The aim of this contribution is to show how the known theories of elastic plates can be extended in order to describe property arbitrary inhomogeneous of the plates materiał for dynamics stability. Each layer being the composite components is taken to be inhomogeneous and anisotropic. The perfect contact between the components of the plate is assumed.

    Dynamics and stability on nonperiodic multilayered plates
    (Wydawnictwo Politechniki Łódzkiej, 1997) Konieczny, Sylwester; Tomczyk, B.
    The method of macro-modelling of nonperiodic multilayered elastic plates has been proposed in [1]. The proposed method is based on certain concepts of the nonstandard analysis [2,3] combined with some a priori postulated physical assumptions. In this paper, using this method the homogenized model of nonperiodic plate will be derived and applied to the evaluation of inhomogeneity effects on a critical force and a free vibration frequency for a simply supported laminated plate.
