The results of experimental study of mechanical properties of samples of sand-lime
brick under dynamic loading are presented. The tests were carried out using the traditional
Kolsky method and its modification - dynamic splitting (the so-called «Brazilian test»). The
laws of change in strength and time properties of the investigated material are determined in
the strain rate range of 3ž102
-2.5ž103 s-1
under compression and in the stress rate range of
2ž101 -3ž102 GPa/s under tension.
Keywords: sand-lime brick, dynamic loading, high-speed deformation, experiments, identification of model parameters |
