摘      要：The fatigue analyses of AlSi7 closed-cell aluminium foam were performed using a real porous model and three different homogenised material models:crushable foam model,isotropic hardening model and kinematic hardening *** numerical analysis using all three homogenised material models is based on the available experimental results previously determined from fatigue tests under oscillating tensile loading with the stress ratio R=*** obtained computational results have shown that both isotropic and kinematic hardening models are suitable to analyse the fatigue behaviour of closed-cell aluminium ***,the kinematic hardening material model has demonstrated significantly shorter simulation time if compared to the isotropic hardening material *** the other hand,the crushable foam model is recognized as an inappropriate approach for the fatigue analyses under tension loading conditions.
