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 high-low velocity impact response of GLAREs
Introduction In modern aerospace engineering and defense industries, impact resistance of materials is a critical factor in ensuring structural safety and durability. One class of materials that has gained significant attention for its superior impact performance is GLARE (Glass Laminate Aluminum Reinforced Epoxy). GLARE is a type of Fiber Metal Laminate (FML) that combines aluminum […]
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 […]
Numerical and Experimental Investigations of S-Glass/Polyester Composite Laminate Plate Under Low Energy Impact
Papers abstract: This paper deals with an analysis of a low energy impact on unidirectional S-Glass/Polyester composite plate. A set of low energy impact tests was carried out on composite plates in a bending configuration. The impact loads were applied using drop-mass tower. The mechanical responses, such as impact force, bending, energy dissipation and damage […]
Analysis of Shearing Capacity of the UHPC Beam Reinforced with Carbon Fiber Truss
Carbon Fiber Truss Ultra-High Performance Concrete (UHPC) is a next-generation concrete known for its exceptional compressive strength, low porosity, and high durability. Despite these advantages, UHPC beams can still experience shear failure, particularly because UHPC, like traditional concrete, has relatively low tensile strength and can be brittle in shear-dominant regions. To address this, the study […]

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 […]
Analysis and simulation of high-velocity impact on a Composite panel(CFRP-Aluminum foam-Aluminum honeycomb-CFRP)
This study presents a comprehensive finite element simulation of a high-velocity impact on a hybrid composite sandwich panel consisting of Carbon Fiber Reinforced Polymer (CFRP) face sheets, an aluminum foam core, and an aluminum honeycomb mid-layer. The structural configuration aims to maximize energy absorption and minimize damage propagation under extreme dynamic loads. A spherical projectile […]
Analysis of the bolted wood-steel panel under tension load
Analysis of Bolted Wood-Steel Panels under Tension Load In modern timber construction, hybrid systems that combine wood and steel elements are increasingly used to optimize structural performance and material efficiency. One such hybrid system is the bolted wood-steel panel, where steel plates are bolted to timber elements to transfer loads, improve stiffness, and enhance connection […]
