    The Influence of Loading Ratio on Fatigue Crack Propagation Through a Bi-material Interface

  • Original language description

    The paper is devoted to fatigue crack propagation in layered materials. The influence of plasticity induced crack closure on threshold values for fatigue crack propagation through interfaces between different materials layers is studied. The main aim wasto estimate the influence of the loading ratio R on threshold values for crack propagation through a bi-material interface as a function of the elastic mismatch of both materials. The finite element method (FEM) is used for numerical calculations. Results obtained for different loading ratios, materials, boundary conditions and magnitude of applied loading can be generalized and used for the design of composite bodies with different material layers.

    Vliv parametru asymetrie cyklu na šíření trhliny přes bi-materiálové rozhraní

  • Czech description

    Práce se zabývá šířením únavových trhlin ve vrstevnatých materiálech. Je studován vliv plasticky indukovaného zavírání trhliny na prahové hodnoty pro šíření trhliny přes rozhraní dvou materiálů. Hlavním cílem je odhadnout vliv velikosti parametru asymetrie cyklu R na prahové hodnoty pro šíření trhliny přes rozhraní dvou materiálů.
