Studying the impact initiation radiation and temperature of polymer bonded explosives in the shock wave flow is crucial for understanding and predicting their reaction kinetics and detonation behavior. This work uses the two-stage light gas gun for shock loading, transient radiation pyrometer temper...

To enhance the heat-resistant performance of on-site mixed emulsion explosives, four kinds of on-site mixed emulsion explosive matrix samples were prepared by adding ammonium formate with different concentrations into corresponding aqueous phase system, respectively. The fluidity, viscoelasticity, v...

As a new alternative fuel, ethanol/methane/hydrogen (C₂H₅OH/CH₄/H₂) is of great significance for the sustainable development of new energy in China. The effects of different equivalence ratios (0.8−1.4), initial pressures (0.1, 0.2 and 0.4 MPa) and initial temperatures (370, 400 and 450 K) on key ex...

The magnetically driven solid liner experiments on the FP-2 device were simulated and analyzed based on the incompressible theoretical model. The simulation results show that the boundary magnetic induction strength formula for the magnetically driven solid liner of the reflux hood structure contain...

To study the impact of the content of carbon nanotubes (CNTs) on the damage evolution and crack propagation in concrete beams, concrete three-point bending beam specimens containing 0, 0.1%, 0.3%, and 0.5% CNTs were prepared. The three-point bending tests were conducted by using the YNS300 electro-h...

In order to explore the failure mechanism of the electronic control module inside the electronic detonator under impact load during the postponement state, a split Hopkinson pressure bar (SHPB) experiment was conducted on the electronic detonator specimens under high overload loading. The failure co...

In order to solve the problem of poor overall blasting effect when using pre-splitting blasting technology in Beiya gold mine, based on RHT damage constitutive model, numerical simulation research on pre-splitting blasting under different hole spacings was carried out by using ANSYS/LS-DYNA numerica...
