    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.
