  2. Stress fracture - Wikipedia

    en.wikipedia.org/wiki/Stress_fracture

    Stress fractures can be described as small cracks in the bone, or hairline fractures. Stress fractures of the foot are sometimes called "march fractures" because of the injury's prevalence among heavily marching soldiers. [2] Stress fractures most frequently occur in weight-bearing bones of the lower extremities, such as the tibia and fibula ...

  3. Fracture (geology) - Wikipedia

    en.wikipedia.org/wiki/Fracture_(geology)

    A fracture will sometimes form a deep fissure or crevice in the rock. Fractures are commonly caused by stress exceeding the rock strength, causing the rock to lose cohesion along its weakest plane. [1] Fractures can provide permeability for fluid movement, such as water or hydrocarbons.

  4. Extensional and intensional definitions - Wikipedia

    en.wikipedia.org/wiki/Extensional_and...

    An extensional definition gives meaning to a term by specifying its extension, that is, every object that falls under the definition of the term in question.. For example, an extensional definition of the term "nation of the world" might be given by listing all of the nations of the world, or by giving some other means of recognizing the members of the corresponding class.

    A stress fracture in the front of your tibia is one of this injuries that frequently requires surgery to heal. A metal rod placed down the center of the tibia is a commonly performed surgery for ...

  6. Fracture mechanics - Wikipedia

    en.wikipedia.org/wiki/Fracture_mechanics

    Fracture mechanics is the field of mechanics concerned with the study of the propagation of cracks in materials. It uses methods of analytical solid mechanics to calculate the driving force on a crack and those of experimental solid mechanics to characterize the material's resistance to fracture.

  7. Fracture - Wikipedia

    en.wikipedia.org/wiki/Fracture

    Fracture is the appearance of a crack or complete separation of an object or material into two or more pieces under the action of stress.The fracture of a solid usually occurs due to the development of certain displacement discontinuity surfaces within the solid.

  8. Fracture in polymers - Wikipedia

    en.wikipedia.org/wiki/Fracture_in_polymers

    Stress Intensity Equation. As the fibrils in the crack begin to rupture the crack will advance in either a stable, unstable or critical growth depending on the toughness of the material. To accurately determine the stability of a crack growth and R curve plot should be constructed. A unique tip of fracture mode is called stick/slip crack growth.

  9. Structural fracture mechanics - Wikipedia

    en.wikipedia.org/wiki/Structural_fracture_mechanics

    It uses methods of analytical solid mechanics, structural engineering, safety engineering, probability theory, and catastrophe theory to calculate the load and stress in the structural components and analyze the safety of a damaged structure. There is a direct analogy between fracture mechanics of solid and structural fracture mechanics:
