Determination of Johnson–Cook Plasticity Model Parameters for Inconel718
Papers abstract: In order to simulate foreign object damage (FOD) phenomenon in aircraft high-pressure compressor blades made of a nickel-based super-alloy, Johnson–Cook (J–C) plasticity model was used. For prediction of material’s plastic behavior at temperature of 400 °C (working temperature of the blades) in the range of strain rates associated with the FOD phenomenon (in […]
Numerical Analysis of Electro-Hydraulic Forming Process by Using Volume Acceleration Loading
Papers abstract: Electro-hydraulic forming is one of the unique processes of high-velocity forming. In this process, the electrical energy is converted into mechanical energy in the form of shock waves within a liquid medium. This energy is utilized to perform redundant work, to overcome friction, and to form the work-piece to its final shape. This […]
Cold spray analysis of an ABS particle with the CEL method
Introduction Cold spray (CS) is a solid-state coating and additive manufacturing process where fine metal or polymer particles are accelerated to high velocities (300–1200 m/s) using a supersonic gas jet (typically air, nitrogen, or helium) and directed toward a substrate. Upon impact, these particles deform plastically and bond to the surface without melting. This unique […]

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. Introduction Over the past few decades, the challenges associated with ageing and deterioration […]
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 […]
