Large Particles

Results of tests using two kinds of nylon reinforced concrete samples are described . In order to deal with the heterogeneous effects of samples resulted from large particles which range from7mm to10mm in diameters, a SPH bar which is 74mm in diameter is used. There seems something new and difficult in the method of testing the concrete’s dynamic compressive responses. The results show that there are obvious strain rate effects in both the two kinds of samples , and the failure strength increases with the increasing of the strain rate.

Kolsky Method

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 5·102-2.5·103 s-1 under compression and in the stress rate range of 2·101-3·102 GPa/s under tension.
