Study of a W-Beam Guardrail Behaviour in Road Safety Barriers

Abstract:

This study presents results regarding a numerical simulation of the plastic displacement of a road guardrail. An experimental study of two different guardrails was conducted in order to collect information regarding displacement due to a determined force behavior. These tests were then simulated in Ansys Workbench to recreate the elastic and plastic domain of the material. The guardrails are two meters long, supported by two simple cylinders while being pressed at the center by a third one. In order to explore the software two different mesh sizes were used to compare their efficiency, being concluded with the comparison between the force-displacement curves of numerical and experimental results.
