Influence of Stress on Void Ratios of Compacted Crushed ...

2019-5-10 · The transfer and evolution of stress among rock blocks directly change the void ratios of crushed rock masses and affect the flow of methane in coal mine gobs. In this study, a Lagrange framework and a discrete element method, along with the soft-sphere model and EDEM numerical software, were used. The compaction processes of rock blocks with diameters of 0.6, 0.8, and 1.0 m

Formula for void ratio | Degree of unsaturation calculator

Here, you are going to learn how to calculate the moister content, void ratio, and degree of saturation of the soil by using the formula for void ratio, degree of saturation, etc.. Before we can calculate the above value we must have to know the meaning of each term related to the soil like void ratio, water content, specific unit weight, etc.
