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 […]
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 corroded steel CHS column strengthened with CFRP under axial load
Introduction Steel Circular Hollow Section (CHS) columns are widely used in engineering structures due to their high strength-to-weight ratio, aesthetic appeal, and excellent performance under axial and bending loads. However, over time, these structural elements are vulnerable to corrosion, especially in harsh or marine environments. Corrosion reduces the cross-sectional area of the steel, compromises structural […]
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 […]
Simulation the CEL water sloshing in the airy CFRP composite tank
The accurate prediction of fluid-structure interaction (FSI) phenomena, such as liquid sloshing, is crucial in the design and safety analysis of lightweight composite tanks used in aerospace and marine applications. Sloshing refers to the oscillatory motion of a liquid inside a container, often induced by external excitations such as acceleration, vibration, or impact. This motion […]
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 […]
