Intermediate Strain - Rate LoadingExperiments - Techniques and Applications
Gas guns and velocity interferometric techniques have been used to determine the loading behavior of AD995 alumina rods 19 mm in diameter by 75 mm and 150 mm long, respectively. Graded-density materials were used to impact both bare and sleeved alumina rods while the velocity interferometer was used to monitor the axial-velocity of the free end of the rods. Results of these experiments demonstr...
متن کاملza Hopkinson bar techniques for the intermediate strain rate testing of bovine cortical bone
Detailed knowledge of the dynamic viscoelastic properties of bone is required to understand the mechanisms of macroscopic bone fracture in humans, and other terrestrial mammals, during impact loading events (e.g. falls, vehicle accidents, etc.). While the dynamic response of bone has been studied for several decades, high-quality data remain limited, and it is only within the last decade that t...

متن کاملCompact SHPB System for Intermediate and High Strain Rate Plasticity and Fracture Testing of Sheet Metal
Anew set-up is proposed to perform high strain rate tension experiments on sheet metal using a compression Hopkinson bar system on the input side.With the help of a custommade load inversion device, the compression loading pulse is converted into tensile loading of the specimen boundary. A tensile output bar is used to measure the tensile force acting on the specimen boundaries. A high speed ca...
متن کاملUltra High Strain Rate Nanoindentation Testing
Strain rate dependence of indentation hardness has been widely used to study time-dependent plasticity. However, the currently available techniques limit the range of strain rates that can be achieved during indentation testing. Recent advances in electronics have enabled nanomechanical measurements with very low noise levels (sub nanometer) at fast time constants (20 µs) and high data acquisit...
