The effect of the petrography, mineralogy, and physical properties of limestone on Mode I fracture toughness under dry and saturated conditions [PDF]

, 2022
Determining the fracture toughness of rock materials is a challenging, costly, and time-consuming task, as fabricating a sharp crack in rock specimens will lead to failure of the specimen, and preparing specimens for determining the rock fracture ...
