Constitutive Response of S65 Beryllium

New data is presented on the constitutive response of S65 Be. Compressive strength tests and split-Hopkinson pressure bar testing were used to examine the response of the material at strain rates of 0.001, 1 and 10$^{\mathrm{3}}$ s$^{\mathrm{-1}}$ over the temperature range 20-400$^{\mathrm{o}}$C. The extent to which this low and intermediate strain-rate data can be captured using a simple rate-dependent strength model will be examined and possible extensions to the model calibration to capture higher rate data will also be discussed.
