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 […]
Bending test analysis of an RC beam with sustainable aluminum boxes filled with UHPC
Abstract This paper presents a numerical analysis of the shear improvement of defected reinforced concrete (RC) beams using sustainable aluminum boxes filled with high performance concrete. Introduction Reinforced concrete (RC) beams are fundamental structural elements in buildings and infrastructures, but they are susceptible to shear failure, especially when compromised by defects such as cracks, voids, […]
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 […]
Strengthening of reinforced concrete slabs using carbon fiber reinforced polymers rods and concrete jacket with a mechanical anchorage system under rigid impact load
Abstract This study presents the development of a new method for strengthening Reinforced Concrete (RC) slabs using Carbon Fiber Reinforced Polymer (CFRP) rods and an Ultra-High Performance Fiber Reinforced Concrete (UHPFRC) external jacket with a Mechanical Anchorage System (MAS) under impact loading.

Analysis of bolts used as shear connectors in concrete-filled steel column
Introduction: Bolts as Shear Connectors in Concrete-Filled Steel Columns Concrete-filled steel tube (CFST) columns are widely used in modern structural engineering due to their excellent load-bearing capacity, ductility, and fire resistance. These composite columns combine the high compressive strength of concrete with the tensile strength and ductility of steel, resulting in efficient and economical load-carrying […]
Low and High velocity impact analysis of a T-shaped steel reinforced concrete column
Steel-reinforced concrete (SRC) columns have been widely used in engineering structures, such as super high-rise buildings, bridges, and railway stations, due to the high bearing capacity and excellent seismic resistance of SRC columns, compared to reinforced concrete (RC) columns. columns. During their service life, these structures may experience various kinds of impact-loading, caused by collision, […]
