EFFICIENT MODELING OF PANEL-LIKE TARGETS IN PERFORATION SIMULATION
This paper studies the application of thin shell elements and solid shell elements in the structural modeling of panel-like targets in finite element perforation simulations. LS-DYNA is used for the present numerical investigation. By comparing the projectile residual velocities and impact pressures given by the shell element targets to those obtained form the solid element target, this work shows that the solid shell element modeling of panel-like targets can not only save a lot of computational effort, but also be able to give good results if the target panels satisfy certain conditions. Therefore, the shell element modeling of targets is an efficient model in the performance simulation of projectiles penetrating through panel-like targets. A preliminary criterion for the validity of the shell element target model is also proposed in the paper.
