NUMERICAL EVALUATION OF THE BEHAVIOR OF A PLATE ON IMPACT WITH A RIGID PROJECTILE USING ELEMENT-FREE GALERKIN METHOD

The impact of the projectile-plate is a complex phenomenon that is analyzed through analytical methods, based on simplifying hypotheses. In addition to the use of empirical laws, these aspects of the projectile-plate interaction and the effects on the structure are studied using numerical methods. This article presents the numerical evaluation of the behavior of a monolithic plate on impact with a rigid projectile using element-free Galerkin method and is shown the evolution of the impact with its effects (deformation with perforation of the plate). Also, an analyze of the variation of the total energy of the plate, kinetic energy of the bullet and bullet velocity over time are presented.
