  4. 23. An Attempt Towards FE-Modelling of Fracture Propagation in Railway Wheels

    University essay from KTH/Spårfordon

    Author : Fred Öhnander; [2018]
    Keywords : Railway wheel; Wheel-rail contact; Wear; Fracture initiation; Physical fracture propagation model; FE-model; Fracture mechanics; XFEM; Inclusion; Järnvägshjul; Hjul-räl-kontakt; Slitage; Sprickinitiering; Fysisk sprickbildningsmodell; FE-modell; Frakturmekanik; XFEM; Imperfektion;

    Abstract : The demand for higher velocities and heavier axle loads for freight trains leads to higher forces on the railway wheels which in turn lead to an increase in stresses on and below the surface of the wheel-rail contact. By time, this induces wear on the wheels which consequently lead to higher maintenance costs and in some cases accidents. READ MORE
