WebIn mineralogy, cleavage and fracture both describe the tendency of a mineral to break. In cleavage, a mineral may split apart along various smooth planes. These smooth planes are parallel to zones of weak … WebIt means that cleavage fracture initiation is controlled by extremely local ‘weak spots’ in the microstructure. A single such weak spot may cause failure of the whole uncracked ligament. This causes cleavage fracture to obey weakest link statistics and to have a specific distribution function.
