Webcleavage easy to see in well-formed bladed crystals (selenite variety) but most occurrences are dull, massive aggregates (alabaster variety) and cleavage is not apparent; twinning Mostly occurs in sedimentary rocks; used for making plaster and some types of wallboard Gypsum CaSO4·2H2O 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. screen lock addons for mac

These planes of relative weakness are a result of the regular locations of atoms and ions in the crystal, which create smooth repeating surfaces that are visible both in the microscope and to the naked eye.

"WebIn animals, cell division occurs when a band of cytoskeletal fibers called the contractile ring contracts inward and pinches the cell in two, a process called contractile cytokinesis. The indentation produced as the ring contracts inward is called the cleavage furrow. Animal cells can be pinched in two because they’re relatively soft and squishy. " - Cleavage typically occurs in
