20.500.12556/DKUM-93626 Time dependent load capacity of the press fit This study investigates the loading capacity of a press fit using experimental, numerical and theoretical methods. Tests on specimens with different interferences showed that the loading capacity increases over time as long as the plasticity remains at the micro level. At larger interferences, the plasticity extends to the macro level, which in the long term means a reduction in the loading capacity of the press fit due to creep. Numerical simulations using finite element modelling showed the influence of surface roughness and time-dependent effect on contact pressure and friction. Models in text books do not take in account plasticity and creep of the material in press fit. The phenomenon can lead to a weakening of the press fit over time. The results highlight the importance of optimizing the interference and surface preparation to improve the loading capacity and joint performance. The article presents an approach for calculating the press fit taking in to account the Bowden Tabor friction model and the visco-plasticity of the material used.
