Meteorite impact events are considered as important influences on the composition of Earth’s early atmosphere, with substantial implications for biological evolution. The physicochemical behavior of sulfur-bearing minerals during such natural impact events is crucial for understanding the role of su...

Diamond anvil cell (DAC) is a kind of widely used static-high-pressure device. Benefitting from its wide pressure range, excellent optical applicability and convenience of use, DAC provides a tremendous boost to the development of high-pressure science. However, at high pressures, factors like solid...

To improve the performance of the CO₂ phase change excitation agent, titanium powder with mass fractions of 2%, 4%, 6%, 8%, and 10% was added to the excitation agent. The contents of ammonium oxalate and salicylic acid were controlled to adjust the zero oxygen balance, respectively. The ignition rel...

In order to study the effect of water content on the performance of porous granular ammonium nitrate on-site mixed ammonium amine explosives, five groups of on-site mixed ammonium amine explosives with different water contents were prepared by controlling the water content in the aqueous phase. We u...

In order to improve the ultimate pressure bearing capacity and increase the volume of the cavity of the belt type ultra-high pressure die, a structure of winding discrete type large cavity ultra-high pressure die was proposed. This die is mainly composed of discreted cylinder, supporting ring and st...

To elucidate the evolution laws of impact velocity of high-pressure pulse water jet and the breakage characteristics of coal under confining condition, a coupled smoothed particle hydrodynamics-finite element (SPH-FEM) algorithm is adopted. A sinusoidal velocity is applied to the plunger inside the ...

In order to investigate the dynamic response process, damage characteristics and damage mode of polyurea coated masonry infill walls with built-in tie reinforcement under close-range explosion load, a series of close-range explosion tests were performed on masonry wall with different polyurea coatin...

Taking Shuitun North Road Station of Jinan Rail Transit Line 7 as an example, a numerical simulation study was conducted to investigate the structural damage and failure effects of the metro structure based on the fluid-structure couple and full restart algorithm in LS-DYNA software. This study focu...

In order to explore the influence of injection pressure on the deflagration characteristics of gasoline in the confined space, a 20 L spherical explosion test device was used to examine the changes of characteristic parameters, i.e., the transient flame propagation and temperature of gasoline mist d...
