Definition of deformation in US English:

deformation

noun

  • 1The action or process of changing in shape or distorting, especially through the application of pressure.

    ‘solid rock undergoing slow deformation’
    • ‘The outer zones accommodate the most deformation and energy absorption, while less deformation takes place the closer the collision approaches the passenger compartment.’
    • ‘Subsequently, between the Late Proterozoic and the Mesozoic, the rocks throughout the region suffered periodic episodes of deformation.’
    • ‘The Catalinas, in all of their grandeur, are going through that process of deformation right now.’
    • ‘As a result, the culverts may undergo excessive deformation or failure rendering the culverts unserviceable.’
    • ‘When the load exceeds a value corresponding to the yield strength, the specimen undergoes gross plastic deformation.’
    • ‘He may have some recollection of a study of cattle in fields downwind of the Steelworks, which indicated that fluorides deposited in these fields eaten by cattle produced discoloration of teeth and deformation of hooves.’
    • ‘It indicates that some deformation and erosion of the Annascaul rocks occurred prior to deposition of the Ballynane Formation.’
    • ‘Bridges can be designed either to remain elastic during the design earthquake or to undergo irreversible but controlled deformation or displacement.’
    • ‘It is a light grey, porphyritic volcanic to subvolcanic rock, which shows almost no deformation.’
    • ‘This again is a criterion of little value in high-strain rocks, where fine banding is a common consequence of deformation.’
    • ‘At high enough stresses, irreversible processes accompany deformation.’
    • ‘The possibility that this scrappy specimen has also undergone very significant deformation should be considered.’
    • ‘Quartz veins are abundant throughout the property and most appear to be related to Cretaceous deformation of the country rocks.’
    • ‘Thus it was able to undergo intense transformations, such as mechanical deformation or metamorphism, but remain always in proximity to the surface.’
    • ‘This process involves two complementary kinds of deformation.’
    • ‘He proposed that insight into the mechanism of rock deformation could be obtained by subjecting confined samples to high pressures in the laboratory.’
    • ‘In physics, something plastic is capable of undergoing continuous deformation without rupture or relaxation; in biology it denotes the ability to form new tissue.’
