Johnson–Holmquist-II model of annealed glass in the dynamic compression test
The Johnson–Holmquist-II (JH-2) model is a widely used constitutive model for predicting the behavior of brittle materials, such as annealed glass, under high-strain-rate conditions, including dynamic compression tests, impacts, and explosions. It was developed by G. R. Johnson and T. J. Holmquist to address the limitations of traditional material models in capturing the complex response […]
Blade creep study with side-by-side built-in vs custom creep models
This CAE demonstration shows a single blade model where you can directly compare a built-in strain-hardening creep material and a custom CREEP subroutine in the same simulation workflow, focusing on blade creep behavior. The study follows a two-step workflow (thermal → creep) and delivers full thermo-mechanical outputs so engineers can evaluate differences in distribution, deformation, […]
Analysis of the blast protection wall system( wood cover-soil)
Terrorism has become a major challenge for the world. Terrorist organizations have raised their activities and their attacks in recent years using explosives. These attacks have left numerous numbers of victims, wreaked massive havoc on basic infrastructure, and increased global concern about the nature of these attacks. Blast wall protection systems can provide a required […]
Analysis of CFRP for seismic strengthening of the RC column
Introduction Reinforced Concrete (RC) columns are vital structural components in buildings and infrastructure. During seismic events, these columns are subjected to complex loading that can lead to cracking, spalling, or even failure. Traditional retrofitting techniques like steel jacketing or concrete encasement can be labor-intensive, costly, and add significant dead load. Analysis of CFRP for seismic […]
Analysis of the laced reinforced concrete with wood cover under air blast load
Introduction The structural performance of buildings and protective systems under extreme loading conditions, such as air blast loads, has become an area of critical interest, particularly for infrastructure security, military applications, and high-risk industrial facilities. One innovative solution to enhance the blast resistance of concrete structures is the use of laced reinforced concrete (LRC) combined […]
Compression test of middle long CFST column with inner I-shaped CFRP Profile
Introduction Concrete-Filled Steel Tube (CFST) columns are widely utilized in modern structural engineering due to their superior axial load-bearing capacity, ductility, and fire resistance. These composite members synergize the compressive strength of concrete and the confinement effect of the surrounding steel tube, making them highly effective in high-rise buildings and bridge piers. To further enhance […]
Bending test analysis of an aluminium-timber composite beam
Introduction Composite beams, made by combining two or more distinct materials, offer unique mechanical advantages by utilizing the strengths of each constituent. One such example is the aluminium-timber composite beam, which merges the high strength-to-weight ratio and corrosion resistance of aluminium with the renewable, lightweight, and ductile properties of timber. The bending test is a […]
Simulation of the Cold Spray Particle Deposition Process
Papers abstract: Cold spray is an emerging solid-state coating technique that enables material deposition without melting. This study simulates the cold spray particle deposition process by analyzing the high-velocity impact of spherical particles onto a flat substrate under various conditions. A novel aspect of this work is the application of the Coupled Eulerian–Lagrangian (CEL) numerical […]
GFRP Reinforced Concrete Slabs in Fire: Finite Element Modelling
Papers abstract: In a fire incident, service loads are present when the structure is engulfed by flames. This sequence—structural loading followed by heat exposure—is used in the finite element (FE) modeling of GFRP-reinforced concrete (RC) slabs. The FE model is validated against two sets of full-scale fire tests on GFRP RC slabs and one set […]
Low-velocity impact behavior of two-way RC slab strengthening with CFRP strips
Papers abstract: There are a lot of studies focused on behavior of reinforced concrete (RC) slabs under static and dynamic loadings in the literature. However, investigations related to Carbon Fiber Reinforced Polymer (CFRP) strengthened RC slabs subjected to impact load are still relatively rare. Consequently, an experimental study was performed in order to determine impact […]
