Airflow through crushed-rock layers

2011 Second International Conference on Mechanic Automation and Control Engineering, 2011
Pressure drops through packed concrete spheres and crushed rocks were investigated by wind tunnel experiments. The diameters of concrete spheres were 0.041 m and 0.052 m, respectively. The mean particle size of the crushed rocks was 0.096 m. The experimental results show that the Ergun equation with revised coefficient values can be used to predict ...

Stress waves in layered rocks

Acta Mechanica, 1992
In this paper two problems will be solved analytically: the reflection of plane stress waves at a free boundary and the reflection and refraction of plane stress waves at a welded interface separating two dissimilar materials. In particular, stress reflection and refraction coefficients will be derived and the superimposed state of stress in regions of
