  • Crash simulations of road safety barriers using LS-DYNA on MPP computing platforms
    Borovinšek, Matej ...
    To reduce the development and testing costs of new safety barrier designs it is advisable to use computational crash simulations for early evaluation of safety barrier behaviour under test vehicle ... impact. To simulate the safety barrier crash test it is necessary to use time steps smaller than 1 ms both to assure the stability of the explicit direct time integration method and to capture the impact behaviour. Reasonable computational times can only be achieved by running the simulations on MPP computing platforms. The paper reports on parametric studies of running crash simulations of safety barriers on PC MPP cluster with different numbers of utilised CPUs, to determine the most appropriate configuration for such simulations. Consequent scalability, stability and accuracy of simulations run on MPP computing platforms are evaluated.
