Abstract: In this paper, a study is presented on the experimental and numerical analysis of the failure process in 5, 10 and 15mm thicknesses of Aluminum 5083 subjected to normal impact by flatnosedprojectiles made of Tungsten. To modeling the behavior of materials, the Johnson-Cook constitutive equation and fracture criterion are used. In all tests, the initial andresidual velocities of the projectile are measured and the ballistic limit of each target plate isprecisely determined. Based on thesemeasurements, the impact versus the residual velocity curves of the plates is constructed and the ballistic limit of each object's velocity is obtained. A finite element analysis of the problem is carried out using the ABAQUS / Explicit finite element code. The results of the numerical analysis are compared with the experiments and the good correlation between these two was found. It is shown that especially results obtained in finiteelement approach are encouraging in terms of predicting the response of the examined plates
