Effect of Initiation Location within Blasthole on Blast Vibration Field and Its Mechanism

Shock and Vibration, 2019
In drill and blast, the explosive filled in each blasthole is cylindrically shaped and generally initiated by the detonator. Thus, the effect of the initiation location must be addressed, as it determines the detonation direction along the entire column ...

Numerical Investigation of Ultra-Wide Low-Frequency Wave Attenuation Using Seismic Metamaterials with Auxetic Slender Strips

Crystals
Seismic metamaterials are an emerging vibration-damping technology, yet concentrating the bandgap in the low-frequency range remains challenging due to the constraints imposed by lattice size.
