摘要：

Load perturbation tests carried out on a 6063 Al-Mg-Si alloy under load rate control verify the predictions of a constitutive model proposed earlier to describe the mechanical response in the dynamic strain ageing regime. The verification is based on a comparison of the measurements with the analytical solution of linearlized constitutive equations for small perturbations as well as with numerical solutions for the full nonlinear constitutive model. The possibility of using this type of perturbative testing for accurate determination of the onset of plastic instability is discussed.
