Density and hardness relationship

WebDensity is the weight or mass of a unit volume of wood, and specific gravity the ratio of the density of wood to that of water. In the metric system of measurement, density and specific gravity are numerically identical; for example, the average density of the wood of Douglas fir is 0.45 gram per cc, and its specific gravity 0.45, because 1 cc ... WebIt is shown that the 0.2 pct offset yield strength of a material (in kg per sq mm) can be obtained from simple hardness measurements using the expression σ y = (H/3)(0.1) m-2, whereH is the Diamond pyramid hardness andm is Meyer’s hardness coefficient. This expression holds for brass, steel in either the cold rolled or tempered condition, and …
