Product Overview:
This tutorial explores the simulation of repeated impacts from a rigid body onto a steel box using Abaqus. The steel box is modeled as a three-dimensional shell, while the rigid projectile is represented as a rigid shell part.

For this analysis, the steel material is applied to the box with elastic-plastic properties, allowing for accurate damage prediction using ductile and shear damage models. Given the nature of the impact and velocity of the rigid projectile, the dynamic explicit procedure is employed. The contact interaction is handled through a general contact algorithm, including a friction coefficient for more realistic behavior. Fixed boundary conditions are applied to both ends of the beam, and an initial velocity is assigned to the rigid body. A fine mesh is necessary for obtaining precise simulation results.

In the initial simulation, outputs such as stress, strain, and damage are calculated following the impact. For the second simulation, residual stress and strain from the first impact are imported into the new model as initial conditions. The results from both simulations can then be compared. The third simulation follows a similar process, with the results from the second simulation imported into the new model to further analyze the repeated impact. By using the ODB output files from each analysis, the results are transferred and applied to the subsequent models.
