This study presents results concerning the stiffness and denting resistance of 6111-T4 aluminium alloy and AZ31B-H24 magnesium alloy. Experimental results of dynamic denting are compared with numerical simulations performed using LS-DYNA software. The experimental tests were performed on 0.9 and 1.09 mm thick plates clamped in a circular area with a diameter of 80 mm. Dynamic denting was accomplished by dropping different indenters from heights ranging from 0.36 to 1.7 m. The obtained experimental results enabled the properties of the two light alloys tested to be compared. The results of the numerical simulations display a good correlation with experiments if dynamic effects are introduced into the constitutive equation of the material through the Cowper-Symonds coefficients.
