Numerical analysis of the CFRP blanket effect on reducing the deformation of pipelines in soil exposed to the Coupled Eulerian-Lagrangian subsurface explosion
Introduction Pipelines are critical infrastructures for the transportation of oil, gas, and other essential resources. Among these, API 5L X65 grade steel pipelines are commonly used due to their strength and cost-efficiency. However, pipelines buried in soil are vulnerable to extreme events such as subsurface explosions, which may result from accidental or intentional detonations. These […]
Analysis of a reinforced concrete (RC) beam with an embedded spiral GFRP bar subjected to air blast loading
🔷 Introduction Reinforced concrete (RC) structures are widely used in both civilian and military infrastructure due to their strength, durability, and cost-effectiveness. However, under extreme loading conditions such as air blast loads—resulting from accidental or deliberate explosions—conventional RC beams may experience severe damage, including spalling, cracking, or even failure. To improve blast resistance, advanced composite […]
Analysis of the blast protection wall system( wood cover-soil)
Terrorism has become a major challenge for the world. Terrorist organizations have raised their activities and their attacks in recent years using explosives. These attacks have left numerous numbers of victims, wreaked massive havoc on basic infrastructure, and increased global concern about the nature of these attacks. Blast wall protection systems can provide a required […]
Analysis of the laced reinforced concrete with wood cover under air blast load
Introduction The structural performance of buildings and protective systems under extreme loading conditions, such as air blast loads, has become an area of critical interest, particularly for infrastructure security, military applications, and high-risk industrial facilities. One innovative solution to enhance the blast resistance of concrete structures is the use of laced reinforced concrete (LRC) combined […]
Analysis of a composite GLARE panel under air blast load
Analysis of a composite panel(CFRP-Ceramic-GFPP) under air blast load
Introduction: In modern engineering, multi-layer composite panels are widely used in defense, aerospace, and infrastructure due to their high strength-to-weight ratio, damage tolerance, and energy absorption capabilities. With increasing threats from blast and impact loading, it’s crucial to assess the performance of these panels under extreme dynamic conditions, such as an air blast explosion. This […]
Finite element analysis on the air blast resistance of stiffened cylindrical tubular aluminum panel
Abstract Aluminum sandwich structures are widely used in modern engineering due to their lightweight, high stiffness, and energy absorption capabilities. These structures typically consist of two strong outer face sheets and a lightweight core (e.g., honeycomb, foam, or lattice). When subjected to air blast loads, such as those from explosions, these structures can help absorb […]
Simulation and analysis of subsurface tunnel with GFRP protection against internal blast using CEL method
Introduction In recent years, the threat of internal explosions within critical underground infrastructure, such as transportation tunnels, utility corridors, and military bunkers, has underscored the need for advanced protective measures. Subsurface tunnels, though naturally shielded from surface threats, are particularly vulnerable to internal blasts due to their enclosed geometry and confined environment. The resulting overpressure […]
Analysis of shock pressure and shock-wave attenuation near a blast hole in rock with CEL method
Introduction Blasting is a widely employed technique in mining, tunneling, and civil engineering to fragment rock masses for excavation and material handling. When an explosive charge is detonated within a blast hole, it generates an intense shock wave that propagates through the surrounding rock medium. The initial shock pressure is extremely high near the borehole, […]
Air blast analysis of a composite panel made of CFRP facing and PET foam core
Introduction to Air Blast Analysis of CFRP-PET Foam Composite Panels 1. Background and Importance Composite sandwich structures, typically comprising Carbon Fiber Reinforced Polymer (CFRP) face sheets and a lightweight core such as Polyethylene Terephthalate (PET) foam, are widely used in aerospace, automotive, and defense industries due to their high stiffness-to-weight ratio, excellent energy absorption, and […]
