  2. Fracture mechanics - Wikipedia

    en.wikipedia.org/wiki/Fracture_mechanics

    Concrete fracture analysis is part of fracture mechanics that studies crack propagation and related failure modes in concrete. [17] As it is widely used in construction, fracture analysis and modes of reinforcement are an important part of the study of concrete, and different concretes are characterized in part by their fracture properties. [ 18 ]

  3. Structural fracture mechanics - Wikipedia

    en.wikipedia.org/wiki/Structural_fracture_mechanics

    Structural fracture mechanics is the field of structural engineering concerned with the study of load-carrying structures that includes one or several failed or damaged components.

  4. 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.

  5. Types of concrete - Wikipedia

    en.wikipedia.org/wiki/Types_of_concrete

    The parts are in terms of weight – not volume. For example, 1-cubic-foot (0.028 m 3) of concrete would be made using 22 lb (10.0 kg) cement, 10 lb (4.5 kg) water, 41 lb (19 kg) dry sand, 70 lb (32 kg) dry stone (1/2" to 3/4" stone). This would make 1-cubic-foot (0.028 m 3) of concrete and would weigh about 143 lb (65 kg). The sand should be ...

  6. Material failure theory - Wikipedia

    en.wikipedia.org/wiki/Material_failure_theory

    Linear elastic fracture mechanics predicts that a crack will extend when the stress intensity factor at the crack tip is greater than the fracture toughness of the material. Therefore, the critical applied stress can also be determined once the stress intensity factor at a crack tip is known.

  7. Gartland & Werley classification - Wikipedia

    en.wikipedia.org/wiki/Gartland_&_Werley...

    Gartland & Werley classification is a system of categorizing Colles' fractures. In the Gartland & Werley classification system there are three types of fractures . The classification system is based on metaphysical comminution , intra-articular extension and displacement, and was first published in 1951.

  8. Structural integrity and failure - Wikipedia

    Collapsed barn at Hörsne, Gotland, Sweden Building collapse due to snow weight. Structural integrity and failure is an aspect of engineering that deals with the ability of a structure to support a designed structural load (weight, force, etc.) without breaking and includes the study of past structural failures in order to prevent failures in future designs.

  9. Concrete - Wikipedia

    en.wikipedia.org/wiki/Concrete

    Concrete is a composite material composed of aggregate bonded together with a fluid cement that cures to a solid over time. Concrete is the second-most-used substance in the world after water, [1] and is the most widely used building material. [2] Its usage worldwide, ton for ton, is twice that of steel, wood, plastics, and aluminium combined. [3]
