Experimental and Numerical Study in Denting Resistance of 6111-T4 Aluminium Alloy
This study presents results of denting resistance of 6111-T4 aluminium alloy. Experimental results of dynamic denting were compared with numerical simulations performed using LS-DYNA software. The experimental tests were performed on 1mm thick plates clamped in a circular area with a diameter of 80mm. Dynamic denting was accomplished by dropping different indenters from heights ranging from 0.36 to 1.7 m. The obtained results indicate a high suitability of the aluminium alloy for use in automotive panels. The results of the numerical simulations display a good correlation with experiments if dynamic effects are introduced in the constitutive equation of the material through the Cowper-Symonds coefficients.
