Behaviour of Cylindrical Steel Drums Under Blast Loading Conditions
Papers abstract: The Buncefield incident in the UK in 2005 involved an explosion of 240,000 m³ of vapour cloud which resulted in considerable damage to properties in the surrounding area. A number of objects that can be used as overpressure indicators such as standard steel drums were located at various points around the site. These […]
Simulation and Analysis of Multi-layered AL-St Composite Materials Under High Velocity Impact
Papers abstract: Finite element (FE) simulations using Abaqus/Explicit are performed to study the deformation behavior of materials under impact loading. Various configurations including monolithic and multi-layered plate having combinations of ceramic, metal and composite material layers are investigated to determine the critical failure velocity Vcf as a function of layer thickness and stacking. While cylindrical […]
Influence of different back laminate layers on ballistic performance of ceramic composite armor
Papers abstract: This paper mainly reported a new type of ceramic composite armor with a back laminate of Ti6Al4V/UHMWPE/Ti6Al4V against the 12.7 mm armor piercing projectile at a velocity of 818 m/s. The mechanism of the whole ceramic composite armor against the projectile, and the function of each layer in the back laminates were systematically […]
Dynamic identification of damage control characteristics of ultra-high performance fiber reinforced concrete
Papers abstract: An experimental investigation has been conducted to assess the damage control properties of ultra-high performance fiber reinforced concrete (UHP-FRC) in comparison to traditional concrete. Five identical reinforced concrete (RC) plates, with the exception of concrete material, are damaged gradually using a repeated impact technique. Damage progression has been evaluated stepwise based on the […]
Deformation behavior of single and multi-layered materials under impact loading
Papers abstract: Finite element (FE) simulations using Abaqus/Explicit are performed to study the deformation behavior of materials under impact loading. Various configurations including monolithic and multi-layered plate having combinations of ceramic, metal and composite material layers are investigated to determine the critical failure velocity Vcf as a function of layer thickness and stacking. While cylindrical […]
Pull-out test analysis of a precast wall panel connection
Precast concrete construction has gained significant popularity in modern building practices due to its advantages in speed, quality control, and cost-effectiveness. A critical aspect of this construction method is the performance of connections between precast components, particularly under various loading conditions. Among the types of connections used, mechanical, embedded, and grouted connections are common in […]
Analysis of an RC column with X-shaped steel section core under the CEL explosion
Introduction In modern structural engineering, improving the blast resistance of buildings is a critical concern, particularly in areas vulnerable to accidental or intentional explosions. Reinforced concrete (RC) columns, as key load-bearing elements, often require additional strengthening to withstand such extreme loads. One promising approach is the incorporation of a steel core, particularly with a unique […]
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 of water sloshing in a cylindrical tank under seismic loading-Acoustic method
Water sloshing in a cylindrical tank under seismic loading is a critical phenomenon in civil and structural engineering, particularly for water supply systems, nuclear power plants, oil storage tanks, and chemical process industries. When a seismic event (earthquake) occurs, the ground motion induces dynamic forces that cause the liquid inside a tank to oscillate. This […]
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 […]
