BUMPERS MADE OF ENERGY-ABSORBING SEMI-RIGID FOAM

The paper gives the material parameters of a semi-rigid polyureth ane foam subjected to impact loads which can be used to produce a comparatively lightweight bumper with conventional dimensions. The properties of such a bumper are described in connection with examples. Finally, initial calculation principles and design indications for dimensioning such a bumper are given.
