CAPACITANCE DETECTORS USED FOR SPLIT HOPKINSON PRESSURE BAR TEST (SHPBT) AND THEIR COMPARISON WITH NUMERIC SIMULATION SHPBT
Original language description
The Split Hopkinson Pressure Bar Test (SHPBT) is used for the determination of mechanical material properties at high strain rates, in this case within 102 to 103s-1. The principle of SHPBT is based on the measurement and evaluation of impact loading that is common in high strain rate processes. Strain gauges are usually used to record impact loading. This paper deals with recording the impact wave using capacitance detectors. SHPBT is a high strain rate test where the compression loading affects a specimen placed between two bars. The duration of impact loading is within the range of 40 to 100 microseconds. The verification of these detectors was performed by comparing an SHPBT experiment and its numerical simulation. The ANSYS LS Dyna 3D software wasused for the numerical simulation. AA 5083 aluminium alloy was the material used for the experiment.
