Vehicle Crash Test Simulation of Roadside Hardware Using LS-DYNA: A Literature Review

During the past several years, thanks in part to Lawrence Livermore National Laboratory and the Federal Highway Administration, there has been a great deal of progress in integrating advanced non linear finite element programs into roadside hardware design and analysis phases. Much work remains, however, before analytical methods in roadside safety research achieve their full potential. Analysis of complex systems is possible since computer software tools are available and computing capabilities continue to improve at a rapid pace. Finite element analysis (FEA) application has evolved from relatively simple impacts to highly realistic interaction problems. FEA is expected to play a vital role in new generation cost-effective roadside hardware design and analysis in the coming years if continued progress is made. LS-DYNA is an FEA application. A summary of the major achievements and key developments of crash test simulation of roadside hardware over the past years is attempted in this literature review. It also tries to inform readers about the current state of knowledge in roadside hardware simulation. The author reviews successful crash test simulations of different applications using roadside hardware type as a basis. Specific virtual crash test models are explained.
