    Experimental model of fracture of functionally graded materials.
    (Polskie Towarzystwo Mechaniki Teoretycznej i Stosowanej, 2010) Jaroniek, Mieczysław
    Fabrication of functionally graded materials (FGM) can be obtained by layeredmixing of two materials of different thermo-mechanical properties with different volume ratios gradually changing from layer to layer such that the first layer has only a few particles of the second phase and the last has the maximum volume ratio of the first phase. Consider a simple model of the functionally graded materials as a multilayered beam bonded to planes having shear modulus Gi and Poisson's ratio [ni]I, respectively, subjected to bending. The behaviour of cracks depends on cracks configuration, size, orientation, material properties, and loading characteristic. The fracture mechanics problem will be approached by making use of photoelastic visualisation of fracture events in the model structure.

    Modelling of annular plates stability with functionally granded structure interacting with elastic heterogeneous subsoil.
    (Polskie Towarzystwo Mechaniki Teoretycznej i Stosowanej, 2014) Perliński, Wojciech; Gajdzicki, Michał; Michalak, Bohdan
    This contribution deals with the modelling and analysis of stability problems for thin composite annular plates interacting with elastic heterogeneous subsoil. The object of analysis is an annular plate with a deterministic heterogeneous microstructure and the apparent properties smoothly varying along a radial direction. The aim of contribution is to formulate two macroscopic mathematical models describing stability of this plate. The considerations are based on a tolerance averaging technique. The general results are applied to the analysis of some special stability problems. The obtained results of critical forces with those obtained from finite element method are compared.
