This study presents, experimentally, similarity and Froude number similitude (FNS) in the dimensionless features of two solitary waves propagating over a horizontal bed, using wave gauges high-speed particle image velocimetry (HSPIV). The have distinct heights H0 (2.9 5.8 cm) still water depths h0 (8.0 16.0 but identical H0/h0 (0.363). Together with geometric free surface elevation wavelength, ...
The number and distribution of joints in rock are closely related to their physical mechanical properties. In this paper, given the propagation law explosive stress waves jointed during blasting influence on dynamic properties crushing energy dissipation rock, parallel simulated construction concrete specimens using a mica sheet. discrete Hopkinson test device is used perform impact test, which...
