Résumé / Abstract
Certain roadside safety barriers are structures made of steel and wood. This kind of structure is currently in fashion in location where the safety equipments need to be discreet (mountains, countryside). In Europe, to be installed on the roadside, the vehicle restraint systems have to pass two crash tests, as defined in the European standard EN1317. Our aim is to develop a dynamic model of the multi material structure in order to understand and optimize the safety barriers i.e. to define the best association of the mechanical properties of both materials. In this paper, 3 point bending experimental tests will be presented at different energy levels. These laboratory tests were used as a basis for the evaluation of a material constitutive law in a numerical parametric study.
