DYNAMIC TENSILE TESTING WITH A LARGE SCALE 33 MJ ROTATING DISK IMPACT MACHINE

K. Kussmaul , C. Zimmermann , W. Issler

A recently completed testing machine for dynamic tensile tests is described. The machine consists essentially of a pendulum which holds the specimen and a large steel disk with a double striking nose fixed to its circumference. Disk diameter measures 2000 mm, while its mass is 6400 kg. The specimens to be tested are tensile specimens with a diameter of up to 20 mm and 300 mm length or CT 15 specimens at various temperatures. Loading velocity ranges from 1 to 150 m/s. The process of specimen-nose coupling is only possible by use of a fast process computer controlling the machine via ultra-fast sensors. In addition to standard measuring techniques an image converter camera is used to register the deformation of the specimen during the impact event. The machine and various measuring and controlling devices are described and preliminary results are presented.
