  2. Work hardening - Wikipedia

    en.wikipedia.org/wiki/Work_hardening

    The stress at initial yield is σ0. Work hardening, also known as strain hardening, is the process by which a material's load-bearing capacity (strength) increases during plastic (permanent) deformation. This characteristic is what sets ductile materials apart from brittle materials. [1] Work hardening may be desirable, undesirable, or ...

  3. Strain hardening exponent - Wikipedia

    en.wikipedia.org/wiki/Strain_hardening_exponent

    Strain hardening exponent. The strain hardening exponent (also called the strain hardening index), usually denoted , is a measured parameter that quantifies the ability of a material to become stronger due to strain hardening. Strain hardening (work hardening) is the process by which a material's load-bearing capacity increases during plastic ...

  4. Autofrettage - Wikipedia

    en.wikipedia.org/wiki/Autofrettage

    Autofrettage. Autofrettage is a work-hardening process in which a pressure vessel (thick walled) is subjected to enormous pressure, causing internal portions of the part to yield plastically, resulting in internal compressive residual stresses once the pressure is released. The goal of autofrettage is to increase the pressure-carrying capacity ...

    en.wikipedia.org/wiki/Cast-in-place_concrete

    Cast-in-place concrete. Animation depicting construction of multi-story building using aluminum handset formwork. Cast-in-place concrete or Cast-in-situ concrete is a technology of construction of buildings where walls and slabs of the buildings are cast at the site in formwork. [1] This differs from precast concrete technology where slabs are ...

  6. Strengthening mechanisms of materials - Wikipedia

    en.wikipedia.org/wiki/Strengthening_mechanisms...

    Strengthening mechanisms of materials. hide. Methods have been devised to modify the yield strength, ductility, and toughness of both crystalline and amorphous materials. These strengthening mechanisms give engineers the ability to tailor the mechanical properties of materials to suit a variety of different applications.

  7. Types of concrete - Wikipedia

    en.wikipedia.org/wiki/Types_of_concrete

    Gypsum concrete is a building material used as a floor underlay [ 43 ] used in wood-frame and concrete construction for fire ratings, [ 43 ] sound reduction, [ 43 ] radiant heating, [ 44 ] and floor leveling. It is a mixture of gypsum, Portland cement, and sand. [ 43 ] One of its advantages is the lightweight nature.

  8. Engineered cementitious composite - Wikipedia

    en.wikipedia.org/wiki/Engineered_cementitious...

    Engineered Cementitious Composite (ECC), also called Strain Hardening Cement-based Composites (SHCC) or more popularly as bendable concrete, is an easily molded mortar -based composite reinforced with specially selected short random fibers, usually polymer fibers. [1] Unlike regular concrete, ECC has a tensile strain capacity in the range of 3 ...

  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.
