For the numerical prediction of the response of concrete structures under extreme dynamic loading, like debris impact and explosions, reliable material data and material models are essential. TNO- PML and the Delft University of Technology collaborate in the field of impact dynamics and concrete modelling. Recently, TNO-PML developed an alternative SHB test methodology which is based on the old principle of spalling, but up to date equipped with diagnostic tools and to be combined with advanced numerical simulations. Data on dynamic tensile strength and, most important, on fracture energy at loading rates up to 1000 GPa/sec are obtained. The paper describes the test and measurement set-up and presents the new test data. The main focus of the paper is on the reconstruction of the dynamic response and failure process.
