The aim of this study is to use numerical simulations for safety assessment of an innovative active head restraint system.This system was developed to protect the head and neck of an occupant in a car without a head airbag during a side impact. Its FE model is c...

The aim of this paper is to contribute to investigation of passive safety of passengers in railway vehicles using numerical simulations. At first, a typical interior of a railway vehicle is created in the Virtual Performance Solution software. It includes finite element models of&#...

A new approach for evaluating Hellmann–Feynman forces within a non-local potential is introduced. Particularly, the case of Hellmann–Feynman theorem applied within density functional theory in combination with nonlocal ab-initio pseudopotentials, discretized by the finite-element method, is discussed in de...
