Modelling the effect of ageing on the yield strength of an aluminium alloy under cyclic loading at different ageing temperatures and test temperatures
Abstract
<p>The simulation of engine components made of age-hardening materials which are subject to thermal–mechanical loads and in homogeneous thermal distribution, places high demands on the material model. To simulate such load cases, a model is required that allows us to consider the effects of ageing on the material properties along the entire temperature profile. This work presents an improved physical-based ageing model which takes different ageing and test temperatures into account. The improved model was fitted to Al-Si-Mg-Cu alloy data under uniaxial strain-controlled isothermal loading conditions at temperatures from room temperature to 250 °C. At the same ageing temperature and test temperature, the peak values of the simulation and test results were within ±2%. This improved model can serve as the basis for the cycle by cycle simulation of thermomechanical fatigue tests.</p>
