Closure to "Assessment of K₀ correlation to strength for granular materials"

The results of the assessment of K_o correlation to strength for granular materials by a team of researchers are discussed. The test results and analysis of K_o measurements provide the basis of the empirical equation in terms of the peak friction angle applicable to both loose and dense sands. The term densified can be distinguished from dense, as densified sand does not mean dense sand. Densification represents a loading or pressurizing process to make changes in the particle arrangement into a denser condition. Dense means a particle arrangement or packing condition as a state description under which the dilative behavior is predominant and governs the entire mechanical behavior of the sand.
