Research on Laplace transform of stress wave propagation relaxation function in multi-layer media
Case Studies in Construction Materials, 2023 There are some difficulties in solving the theory of stress wave propagation in multi-layer media. To solve the problem of stress wave propagation in multi-layer media under the impact load, this paper theoretically makes further derivation and ...

Crack propagation and coalescence mechanism of double-hole cumulative blasting in coal seam
工程科学学报, 2020 This paper focuses on the radius of coal failure zones under cumulative blasting with shaped charge. Based on the analysis of the mutual superposition effect of the explosion stress waves during the simultaneous detonation of two blastholes, a numerical ...

Stress Wave Propagation in Rock [PDF]
, 1979 There are a number of pressing engineering and geophysical problems involving transient finite deformation of rock and rock masses. An interesting and representative example is a borehole drilled into a geological formation which is packed with explosives and detonated in an attempt to rubblize the adjacent medium for the purpose of in situ resource ...
