Title: CHARACTERIZING GUARDRAIL STEEL FOR LS-DYNA3D SIMULATIONS
Accession Number: 00727325
Record Type: Component
Availability: Find a library where document is available Abstract: Finite-element models have three parts: geometry, connections, and material properties. As the visible parts of a model, geometry and connections are generally carefully considered. Material properties often are not chosen with the same degree of care although they are equally important to obtaining good results. Accurate simulations of vehicles striking roadside hardware require an understanding of both the material behavior and the mathematical material models in LS-DYNA3D. A method for comparing LS-DYNA3D simulations with typical ASTM materials tests is described. The behavior and modeling parameters of guardrail steel (AASHTO M-180 Class A Type II) are examined in this study. Experimental and simulation results of quasistatic coupon tests are compared for AASHTO M-180 Class Type II guardrail steel, and parameters for guardrail steel are recommended.
