гомогенна перешкода; використання двовимірного лагранжевого підходу (2D); метод Smooth Particle Hydrodynamics (3D)Abstract
The article presents the results of comparison of the simulation of the penetration process with a different shape of the main part of the homogeneous obstacle using the two-dimensional Lagrangian approach (2D) and the Smooth Particle Hydrodynamics (3D) method. The obtained results show the possibility of using both approaches to break through the homogeneous obstacles, taking into account the type of puncture. According to studies, the use of the Smooth Particle Hydrodynamics method is more acceptable in the study of penetration due to a much lower error in the field experiment and a more reliable description of the nature of the various types of penetration.
