Analysis of a Phantom aircraft collision on a concrete wall
Introduction The analysis of a Phantom aircraft collision on a concrete wall is a specialized case study in the field of structural impact dynamics and crashworthiness. This analysis typically refers to experimental and computational investigations carried out to understand the behavior of reinforced concrete structures when subjected to high-velocity impacts from large, heavy objects — […]
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 […]
Glass analysis package in Abaqus
Introduction to Glass Analysis and Simulation Using the Johnson-Holmquist Model in Abaqus Glass is a brittle material widely used in defense, automotive, civil, and aerospace engineering due to its transparency, hardness, and relatively low density. However, its failure behavior under dynamic loading, such as high-velocity impacts, differs significantly from metals or polymers. Unlike ductile materials, […]
Analysis of the aluminum multi-particle impact in the cold spraying process
Introduction Cold spraying is an advanced coating technique that involves the acceleration of solid powder particles—typically metals like aluminum—to supersonic velocities using a high-pressure gas stream, usually at relatively low temperatures (below the melting point of the material). These particles impact a substrate and bond with it through plastic deformation rather than melting and solidifying, […]
Analysis of the UHPC beam-column joint reinforced with steel angle and bolts
Introduction Beam-column joints are critical components in reinforced concrete (RC) frame structures, especially in seismic regions where they are subjected to complex loading conditions such as bending, shear, and torsion. The integrity and ductility of these joints significantly influence the overall seismic performance and structural resilience of buildings. Conventional concrete often struggles to meet the […]
Analysis of ceramic plates as shielding for the UHPC panel against projectile penetration
Introduction In modern protective structures, the threat posed by high-velocity projectiles—whether from military weaponry or industrial accidents—has necessitated the development of advanced armor systems. Among these, Ultra-High-Performance Concrete (UHPC) has emerged as a promising material due to its exceptional compressive strength, ductility, and energy-absorbing capabilities. However, UHPC alone may not provide sufficient resistance against high-speed […]
Bending test analysis of the steel-concrete composite beam in the SRC structure
1. Introduction Steel-Reinforced-Concrete (SRC) structures are hybrid structural systems that combine the compressive strength of concrete with the tensile and ductile capabilities of embedded steel elements. A key component of SRC systems is the steel-concrete composite beam, which integrates structural steel sections (I-beams or H-sections) and reinforced concrete into a unified structural member. The bending […]
Analysis of aluminum-wood composite panels under high-velocity impact
Introduction Aluminum-wood composite panels are hybrid materials that combine the high strength and lightweight characteristics of aluminum with the natural energy absorption and aesthetic qualities of wood. These materials are increasingly used in sectors such as construction, transportation, and protective structures where both structural performance and impact resistance are critical. One area of growing interest […]
Analysis of the Seismic Behavior of Semirigid Steel Frame with X-Shaped Brace
Introduction Steel frame structures are widely used in modern construction due to their high strength, ductility, and adaptability to various architectural designs. Traditionally, these frames are modeled as either rigid or pinned; however, real-world behavior often falls between these extremes, hence the term “semirigid connections.” These semirigid joints exhibit partial moment resistance and rotational flexibility, which significantly […]
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 […]
