in design of defense structures, concrete are often used to provide protection against incidental dynamic loadings such as the impact of a steel projectile. in the present study, a new analytical model is proposed to predict penetration depth into concrete targets by ogive nose projectile. hence, to ­ develop the model and simulate penetration of high velocity ogive-shape nose steel projectiles...

The present work will introduce some of the resent developments in the Incompressible CFD (ICFD) solver currently under development in LS-DYNA. The main feature of this solver is its ability to couple with any solid model to perform Fluid-Structure interaction (FSI) analysis. Highly non-linear behavior is supported by using automatic re-meshing strategies to maintain element quality within acce...

Abstract For the information acquisition of whole motion a projectile with sliding driving band in gun bore, nonlinear dynamic explicit finite element software LS-DYNA was used. The pressure-time curve bore is equivalent to boundary input condition gun, and large deformation process described by ALE algorithm. simulation results show that number calculated data are good agreement experimental v...
