Plastic Shear Properties of Metals and Alloys at High Strain Rates

reportActive / Technical Report | Accession Number: AD0770754 | Open PDF

Abstract:

An account is given of experiments using a torsional split Hopkinson- bar apparatus, by means of which short tubular specimens can be subjected to shear strain rates up to 3000sec. The methods of calibration and data reduction are described, and static and dynamic shear properties are given for mild and stainless steel, titanium, copper, yellow brass and aluminum. Some of the results are compared with existing data obtained in shear, tension and compression tests on similar materials, and the significance of the observed rate dependence of the flow stress is briefly discussed.
