Abstract

Split Hopkinson bar set-ups are considered to be valuable, if not indispensable, to study the strain rate dependent mechanical behaviour of materials. In recent years results of SHB experiments on a wide range of materials have been reported in literature. Given their importance for crash relevant applications, special attention has been paid to the tensile properties of steel sheets used in the automotive industry. For tensile experiments most often dogbone-shaped geometries are used, however with widely divergent dimensions. In this contribution results of an extensive experimental study on the influence of the specimen ge
