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 to replicating the high-velocity impact simulation from the referenced ISI paper using Abaqus/Explicit. The model focuses on a concrete slab penetrated by an ogive-nosed steel projectile, with simplified reinforcement for computational efficiency. Key simulation steps include:

• Creation of 3D deformable concrete slab and discrete rigid projectile.
• Assignment of JH-2 material model to concrete and elastic-plastic properties to rebar.
• Mesh refinement strategies for impact accuracy (global/local seeding).
• Dynamic explicit analysis with velocity-boundary conditions.
• Post-processing for damage (SDV_DAMAGE), velocity decay, and internal energy.

In this tutorial, high-velocity impact dynamics are simulated, according to data from the work of Oucif & Mauludin.
