N2 - The present study discusses the finite element modeling and simulation strategy of projectile impact on thin ductile target like aluminum. Ogive nose projectile was chosen to impact on aluminum target normally by velocities at and above the ballistic limit of the plate. Abaqus/Explicit finite element code was used to model the problem. To define the thermo-viscoplastic behavior of the metal target, Johnson-Cook flow stress was used in conjunction with damage initiation criterion to predict the complete perforation process. Further, Hillerborg’s damage evolution proposal, based on stress-displacement response, was followed to observe the damage response after the failure has initiated in the material. Various parameters, like choice of element size, hourglassing, aspect ratio of elements, etc. which plays an important role in the simulation, have been studied. The result obtained with the presented model is compared with the results from the literature, and good agreement between them was found.
