摘要
The results of experimental study of mechanical properties of samples of lime-sand 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, strain, time properties and energy intensity of the investigated material are established in the strain rate range of 5.10(2)-2.5.10(3) s(-1) under compression and in the stress rate range of 2.10(1)-3.10(2) GPa/s under tension.
