“…Adjacent barrier guideways bolt connection were modelled using discrete beams [1,2]. This approach was introduced and used with success in several papers concerning crash tests numerical simulations [9,11,20] LS-DYNA's material law used for the bolts in the model is *MAT_NONLINEAR_PLASTIC_DISCRETE_BEAM. In general it acts as a cluster of 6 springs operating with adequate stiffness, assigned to the directions of degrees of freedom in each of the beam nodes.…”

The subject of this study is performance of N2/W4/A steel road safety barrier investigated in numerical simulations. System was checked under several types of initial conditions, which were assumed basing on the TB11 and TB32 normative crash tests. The main goal of present study is to investigate the relationship between initial conditions (angle and velocity) of the impact and the severity indices (associated to the vehicle occupant) during the collision. Obtained performance parameters and impact severity indexes may be considered reasonable. Results of the simulations facilitates the deep insight into vehicle crash mechanics phenomena.

“…This method is widely used in modelling vehicle collision against various types of road restrained systems [11][12][13][14]. Validation procedures have been described in European Standards [3,4], their direct use can be found in [15,16]. Validation of the concrete road safety barrier was performed showing that the obtained numerical response is correct.…”

The paper concerns with the analysis of normative requirements pertaining to experimental setup of a crash test and its numerical modelling. An overview of parameters describing the collision of a vehicle with a road restraining system is presented. A short description of a concrete road safety barrier is presented. A brief description of numerical modelling procedures for crash tests is given as well. The parametric influence analysis is performed of the acceleration recording time on various crash test functionality parameters The simulations are carried out using LS-DYNA finite element code with a solver version R.8.1

“…One of the most popular systems is LS-DYNA explicit dynamic finite element code [3,4]. It is widely used tool for crash tests simulations for various types of road restraining systems [5][6][7][8][9][10][11][12] or other special events [13][14][15][16]. Thus, numerical methods allow engineers to apply the virtual testing environment in broad spectrum of applications aimed at improving the road safety.…”

This paper discuss the influence of selected factors on the performance of a concrete road barrier H2/W5/B. Modelling techniques of a concrete road safety system were briefly discussed. Comparison to the full scale crash test results has been shown. The concrete road safety barrier has been investigated for evaluation of the overall damage after collision under various initial conditions. The failure assessment criterion has been proposed and it was derived from a qualitative comparison of the numerical results with the full scale crash test data. Impact severity indexes have been calculated and discussed.
