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 […]
Analysis of adhesively bonded cross-laminated timber-concrete composite under close blast explosion test
The increasing demand for sustainable and resilient building materials has driven the development of hybrid structural systems that combine the advantages of different materials. One such system is the cross-laminated timber–concrete (CLT–concrete) composite, which leverages the high stiffness and compressive strength of concrete with the lightweight, renewable, and ductile characteristics of cross-laminated timber (CLT). These […]
Blast resistance behavior of interior voided slab-column connections using steel sheets and CFRP reinforcement
Introduction to Blast Resistance Behavior of Interior Voided Slab-Column Connections Using Steel Sheets and CFRP Reinforcement Background Slab-column connections are critical structural elements in modern buildings, particularly in high-risk environments where blast resistance is a design consideration. Traditional reinforced concrete (RC) slab-column connections may experience punching shear failure under blast loads, leading to catastrophic structural […]
