Ballistic Impact on Ceramic/Aramid Armour Systems

This paper examines how hydrodynamic forces govern damage and penetration in ceramic/aramid armor under high-speed ballistic impact. Using SPH and finite element methods in AUTODYN, the study explores how thickness ratios and shape configurations influence crack patterns, energy dissipation, and ballistic resistance. Parametric simulations reveal optimal composite layering strategies that balance performance and material efficiency.

High Speed Impact on Ceramic Plates

This paper presents a simulation-based investigation into the hydrodynamic response of ceramic armor plates under high-speed projectile impact using SPH in Autodyn. The study models the fracture and energy dissipation behavior of the ceramic plate, emphasizing the role of particle-based hydrodynamics and pressure-dependent failure. Results demonstrate the utility of SPH in resolving complex damage mechanics for shape and material optimization of protective systems.

Protecting Buildings from Bomb Damage

Commission on Engineering and Technical Systems

This study examines how explosion-induced hydrodynamic forces impact civilian buildings and explores adapting military blast-mitigation technologies for civilian use. It highlights structural behavior, pressure dynamics, and simulation-based design, recommending shape-focused strategies, training, and tools to enhance blast resistance.

Rational Analysis of Tunnels Subjected to Different Explosive Loads

Dr. Adel Mahmoud Belal

This work presents a hydrodynamics-informed finite element analysis of tunnel structures under explosive loading. Through parametric modeling and advanced material characterization, it establishes simplified predictive equations to assess the deformation and stress distribution in rock tunnels. The simulations enhance understanding of shock propagation and structural failure mechanisms critical to tunnel safety.

Response of Reinforced Concrete Structures to Aircraft Crash Impact

T. Wilt, A. Chowdhury

This paper explores the dynamic interaction between an aircraft and reinforced concrete structures under crash conditions using SPH and LS-DYNA. By simulating hydrodynamic deformation patterns and calibrating material response, it validates the methodology against full-scale test data. The approach supports optimized structural safety evaluations for critical infrastructure under impact threats.
