Abstract EN

The subject of the paper is a description of a simple test from the field of terminal ballistics and the handling of issues arising during its simulation using the numerical techniques of the finite element method.

With regard to the possible excessive reshaping of the finite element mesh there is a danger that problems will arise such as the locking of elements or the appearance of negative volumes.

It is often necessary to introduce numerical extensions so that the simulations can be carried out at all.

When examining local damage to structures, such as the penetration of the outer shell or its perforation, it is almost essential to introduce the numerical erosion of elements into the simulations.

However, when using numerical erosion, the dissipation of matter and energy from the computational model occurs in the mathematical background to the calculation.

It is a phenomenon which can reveal itself in the final result when a discrepancy appears between the simulations and the experiments.

This issue can be solved by transforming the eroded elements into smoothed particle hydrodynamics particles.

These newly created particles can then assume the characteristics of the original elements and preserve the matter and energy of the numerical model.
