Original Abstract

The paper describes some negative aspects of high speed loading simulations by using the finite elements method. A simple terminal ballistics experiment illustrates the issue. It consists in a collision of a high speed flying fragment with a concrete target. Penetration and spalling of the concrete target surface are considered as main characteristics of the failure. A large elements deformation in the simulations causes numerical problems such as elements locking, negative volumes formation and increased computational time. These negative simulations aspects can be removed by using some numerical tools such as elements erosion and eroded mass transformation into smoothed particle hydrodynamics. The both numerical tools are explained and their connection with a material model physical nature as well as their application in the simulation are described afterwards. The results show the functionality of these tools in the end of the paper.
