Optimization Model and Visualization Simulation of Projectile Penetration into Concrete

Using visual simulation technology to investigate the damage mechanism and target response of projectile penetration into concrete is an important research topic in the field of explosive impact. Concrete, as a common building material, has complex and varied damage behavior when subjected to explosive impact or high-speed projectile penetration. Herein, a visual simulation method is introduced, which is based on the combination of theoretical research and visualization technology. An optimized model of penetration calculation is established based on the theory of cavity expansion, which can predict the characteristics of the penetration depth of concrete penetrated by the projectile. Using a visualization physics engine, the trajectory of the projectile, the aperture of the open pit, the damage of the target slab, and the debris splash are carefully characterized and simulated, which enhances to the realism and reliability of the scene. The developed visual simulation system can not only observe the process of projectile penetration into concrete from multiple perspectives, but also efficiently and accurately analyze and predict the damage behavior and dynamic response of projectile penetration into concrete targets. It has important application prospects in the design and safety assessment of construction projects, providing a novel perspectives for understanding and exploring the mechanism of concrete penetration.
