Abstract
This paper describes the measurement of the tensile
strength and the fracture energy of High Performance Concrete (HPC) at high
strain rates between 10/s and 100/s. Therefore a Hopkinson-Bar is modified
in order to perform spall experiments. The spall strength is determined from
the pull-back velocity at the free end of the specimen. The fracture energy
is calculated from the dissipated energy while crack opening takes place.
The paper provides Dynamic Increase Factors (DIF) for the tensile strength
and the fracture energy of HPC.
