Web7 de jul. de 2024 · Six cleavage planes can form a 12-sided shape = dodecahedral cleavage (e.g., sphalerite). What is the difference between cleavage and fracture? Cleavage is the property of a mineral that allows it to break smoothly along specific internal planes (called cleavage planes) when the mineral is struck sharply with a hammer. 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.
