Cohesion yield stress什么意思
WebJul 17, 2024 · Examples. A common example of cohesion is the behavior of water molecules. Each water molecule can form four hydrogen bonds with neighbor molecules. … WebJul 1, 2013 · Shear testing at different preconsolidation stresses generates information on failure or yield loci. A yield locus is the relationship between shear stress, τ, and normal stress, σ, which has been reported to exhibit a concave curvature, see for example [2], [5]. Extrapolation of the yield locus to the ordinate gives a value of powder cohesion.
