Physical Properties of Granular Fertilizers and Impact on ...

Compressive Or Crushing Strength. Compression across the grain is very closely related to hardness and transverse shear. There are two ways in which wood is subjected to stress of this kind, namely, (1) with the load acting over the entire area of the specimen, and (2) with a load concentrated over a portion of the area. (See Fig. 2.)
