Papers abstract:

A numerical simulation of a high-velocity impact of reinforced concrete structures is a complex problem for which robust numerical models are required to predict the behavior of the experimental tests. This paper presents the implementation of a numerical model to predict the impact behavior of a reinforced concrete panel penetrated by a rigid ogive-nosed steel projectile. The concrete panel has dimensions of 675 mm × 675 mm × 200 mm, and is meshed using 8-node hexahedron solid elements. The behavior of the concrete panel is modeled using a Johnson-Holmquist damage model incorporating both the damage and residual material strength. The steel projectile has a small mass and a length of 152 mm, and is modeled as a rigid element. Damage and pressure contours are applied, and the kinetic and internal energies of the concrete and projectile are evaluated. We also evaluate the velocity at different points of the steel projectile and the concrete panel under an impact velocity of 540 m/s.

Product Overview:
This tutorial provides a step-by-step guide for simulating high-velocity impact on a reinforced concrete panel using Abaqus/Explicit, based on the referenced ISI paper. The model replicates the impact of a rigid projectile (540 m/s) on an RC panel, incorporating material damage, energy absorption, and fracture dynamics. Key simulation steps include:

• Geometry setup (half-symmetry concrete panel, ogive-nosed projectile, and reinforcement beams).
• Material assignment (JH-2 for concrete, elastic-plastic steel for projectile/rebars).
• Meshing refinement at the impact zone with element deletion.
• Boundary conditions (symmetry, encastre, and projectile velocity).
• Dynamic explicit analysis (0.001 s duration) and post-processing (pressure/damage contours)

In this tutorial, high-velocity impact and perforation of an RC panel are simulated, according to data from the work of Oucif & Mauludin.
