Rock failure relationships - PetroWiki

Rock failure definition. Stress strain relationships in rocks examined the elastic behavior of rocks, which was largely reversible. Here we deal with permanent deformation. By rock failure, we mean the formation of faults and fracture planes, crushing, and relative motion of individual mineral grains and cements.

IMPACT STRENGTH OF BRITTLE MATERIALS (ROCKS)

The rock strength coefficient FN is graphically determined from the curve (FΝ, Ν) and corresponds to the minimum value of the curve. This minimum value of FN is, by definition, the impact rock strength coefficient (FN), as representing the optimum specific crushing energy (minimum impact energy per unit volume of -0.5 mm material).
