Simuleon B.v Blog Simulation of the Ballistic Behaviour of the Thin Steel Plate in Abaqus/Explicit

Summary This Technology Brief presents the results of a numerical simulation of the perforation of a thin steel plate by a rigid projectile in Abaqus/Explicit [1]. The thickness of a square plate with a span of 100 mm is 1 mm. In contrast, the mass of a projectile with a diameter of 13 mm is 30 g. The residual velocity of the projectile is determined for an initial velocity of less than 180 m/s. The influence of the projectile shape on the residual velocity and the failure pattern of the perforated plate is determined. These results are compared with experimental tests in which both the VR -  V0 curve and the failure pattern are determined directly. The most important element of the simulation is the use of a constitutive model, ensuring that the constitutive model is sufficiently sensitive to the strain rate [2] and that an appropriate failure criterion is used taking into account the influence of the triaxiality factor [3].
