A finite element study carried out using LS DYNA and aimed to simulate the monotonic pull-out test of deformed steel rebar embedded in concrete is presented this paper. Three models interface between well-confined concrete, i.e. perfect bond model two bond-slip are observed compared. Bond stress-slip response obtained numerically validated with experimental data empirical equations available fr...

Many scholars have used experimental research methods to conduct extensive on the impact energy release behavior of Polytetrafluoroethylene(PTFE)/Al reactive materials. However, in numerical simulation, PTFE/Al still lacks calculation parameters behavior. In order obtain simulation ignition, Hill mixture law was calculate material (mass ratio 73.5/26.5), and according Hugoniot curve γ state equ...

This research work aimed to enhance the crashworthiness of existing automobile bumper minimize crash injuries. As per simulation results weight carbon polyamide-based is reduced in comparison with steel by 9.7 kg or 47.5%, this reduction 38% increase fuel economy has been estimated. The energy absorption capability polyamide improved from and aluminum 11.15% 16.3% respectively modification, imp...

in this article, finite element method and ale formulation were used to numerically simulate impact of low-velocity specific projectiles with water surface. for the simulation, ls-dyna finite element code was used. material models which were used to express behavior of air and water included null material model. for the projectile, plastic-kinematics material model was applied. mie-gruneisen eq...

Columns are the key load-bearing elements in frame structures and exterior columns are probably the most vulnerable structural components to terrorist attacks. Column failure is normally the primary cause of progressive failure in frame structures. A high-fidelity physicsbased computer program, LS-DYNA was utilized in this study to provide numerical simulations of the dynamic responses and resi...

In this study, head injury criteria (HIC) and chest severity index (CSI) assessments are made based on finite element simulation. Simulations are carried out through nonlinear finite element analysis software LS-Dyna. The effect on the occupant’s injury of introducing aluminum alloy, AA5182, to automotive side members is highlighted in comparison to the existing model made of steel. The HIC and...
