This paper deals with an experimental device combined with a computational
procedure in order to determine the rise in temperature obtained during com
pressive Hopkinson tests. These tests consist of a dynamic compression of a
sample between two bars. Since the useful diameter of the specimen is smal
ler than the diameter of the bars, we obtain a dynamic viscoplatic compress
ion combined with a rise in temperature within the sample. This phenomenon
is measured by means of an infrared camera. This work presents the difficul
ties which have been met during the experiments and the chosen solutions in
order to capture the rise in temperature just after loading. Then, the tes
ts are simulated using the ABAQUS finite element code and the numerical res
ults are compared with experimental data.
