A well stimulation technique in which fluids are pumped into a formation under extremely high pressure to create or enlarge fractures for oil and gas to flow through Proppants such as sand are injected with the liquid to hold the fractures open
Method of dividing an electoral group into multiple districts to reduce their electoral influence Ant: packing
A technique in which a mixture of water and sand is forced down an oil well (or similar) in order to create fractures in the oil-bearing rock and thus release more oil
Breach in continuity of a bone Types of fractures include simple, compound, comminuted, greenstick, incomplete, impacted, longitudinal, oblique, stress, or transverse
A general term to include any kind of discontinuity in a body of rock if produced by mechanical failure, whether by shear stress or tensile stress Fractures include faults, shears, joints, and planes of fracture cleavage
the act of cracking something breaking of hard tissue such as bone; "it was a nasty fracture"; "the break seems to have been caused by a fall" fracture a bone of; "I broke my foot while playing hockey" break (a bone); "She broke her clavicle" become fractured; "The tibia fractured from the blow of the iron pipe" violate or abuse; "This writer really fractures the language" break into pieces; "The pothole fractured a bolt on the axle" interrupt, break, or destroy; "fracture the balance of power
Breach of continuity of a bone Types of fractures include simple, compound, comminuted, greenstick incomplete, impacted, longitudinal, oblique, stress, or transverse
(geology) a crack in the earth's crust resulting from the displacement of one side with respect to the other; "they built it right over a geological fault"
To cause a fracture or fractures in; to break; to burst asunder; to crack; to separate the continuous parts of; as, to fracture a bone; to fracture the skull
If something such as a bone is fractured or fractures, it gets a slight crack or break in it. You've fractured a rib, maybe more than one One strut had fractured and been crudely repaired in several places He suffered a fractured skull
If something such as an organization or society is fractured or fractures, it splits into several parts or stops existing. His policy risks fracturing the coalition It might be a society that could fracture along class lines. a crack or broken part in a bone or other hard substance. In mineralogy, the appearance of a surface broken in directions other than along cleavage planes. There are several kinds of fractures: conchoidal (curved concavities resembling shells, as in glass); even (rough, approximately plane surfaces); uneven (rough and completely irregular surfaces, the commonest type); hackly (sharp edges and jagged points and depressions); and splintery (partially separated splinters or fibres). In engineering, rupture of a material too weak to sustain the forces on it. A fracture of the workpiece during forming can result from flaws in the metal; these often consist of nonmetallic inclusions such as oxides or sulfides trapped in the metal during refining. Laps are another type of flaw, in which part of a metal piece is inadvertently folded over on itself but the two sides of the fold are not completely welded together. Structural and machine parts subject to vibrations and other cyclic loading must be designed to avoid fatigue fracture. See also ductility, metallurgy, strength of materials, testing machine. Break in a bone, caused by stress. It causes pain, tenderness, and inability to use the part with the fracture. The site appears deformed, swollen, and discoloured, and the bone moves in abnormal ways. It must be protected from weight bearing and movement between the broken ends while it heals, producing puttylike new tissue that hardens to join the broken pieces together. Complications include failure to heal, healing in the wrong position, and loss of function despite good healing. Fractures in joints present a particularly serious problem, often requiring surgery.
