In this tutorial, the Bullet penetration model using large deformation explicit finite element simulations of rapid penetration in soil in Abaqus software has been studied. The bullet is modeled as a three-dimensional part, and the soil as an Eulerian model. You can see a figure of the assembled parts below ...

In Abaqus, CEL (Coupled Eulerian-Lagrangian) and Eulerian analysis are advanced techniques used to model complex problems involving large deformations, fluid-structure interactions, and multiphase flows. These methods are particularly useful when traditional Lagrangian approaches struggle to handle severe mesh distortions or when fluid behavior dominates the problem Eulerian Analysis Eulerian analysis is a framework where ...

The primary motivation of this study was the development and implementation of an explicit nonlin-ear dynamic finite element based methodology for investigating the crashworthiness of small lightweight rigid impacting into soft soil.The crash dynamics of aircraft are highly dependent on the characteristics of the impact terrain, as different terrains produce ...
