Numerical investigation of concrete-filled double skin steel tubular structure subjected to underwater explosion
Concrete-filled double-skin steel tubular (CFDST) structures are a type of composite structure that consists of two concentric steel tubes (an inner and outer steel tube) with concrete filled in the annular space between them. These structures are increasingly used in offshore, marine, and defense-related applications due to their excellent strength-to-weight ratio, enhanced energy absorption capacity, […]
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 […]
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 […]
Simulation composite pipe(CFRP+Concrete-Steel-Concete-Steel) undder
This study investigates the dynamic response of a multi-layered composite pipe structure, composed of CFRP, concrete, and steel layers, subjected to internal blast loading. A high-fidelity finite element model is developed using Abaqus Explicit, incorporating advanced material models, contact definitions, and blast loading conditions. The objective is to assess the blast resistance and failure mechanisms […]
