La déformation dynamique des dispositifs de sécurité routière sous le choc de véhicules: methode de mesure et conception du dispositif.

A study to the parameters of the dynamic deformation of the safety fence and their equilibrium is made. A first condition is the exact measurement of the dynamic curve, transitory phenomenon in the space and the time. After calculations and stastical and dynamical experiments, different solutions are presented which can realise safety fences of variable rigidity.
