  2. Lankford coefficient - Wikipedia

    en.wikipedia.org/wiki/Lankford_coefficient

    The Lankford coefficient (also called Lankford value, R-value, or plastic strain ratio) [1] is a measure of the plastic anisotropy of a rolled sheet metal. This scalar quantity is used extensively as an indicator of the formability of recrystallized low-carbon steel sheets.

  3. Die forming (plastics) - Wikipedia

    en.wikipedia.org/wiki/Die_Forming_(Plastics)

    A die in polymer processing is a metal restrictor or channel capable of providing a constant cross sectional profile to a stream of liquid polymer.This allows for continuous processing of shapes such as sheets, films, pipes, rods, and other more complex profiles.

  4. Monobloc engine - Wikipedia

    en.wikipedia.org/wiki/Monobloc_engine

    De Dion-Bouton engine with monobloc cylinder heads, but cylinders separate from crankcase c. 1905 [1]. A monobloc or en bloc engine is an internal-combustion piston engine some of whose major components (such as cylinder head, cylinder block, or crankcase) are formed, usually by casting, as a single integral unit, rather than being assembled later.

  5. Sheet metal - Wikipedia

    en.wikipedia.org/wiki/Sheet_metal

    Sheet metal is available in flat pieces or coiled strips. The coils are formed by running a continuous sheet of metal through a roll slitter. In most of the world, sheet metal thickness is consistently specified in millimeters. In the U.S., the thickness of sheet metal is commonly specified by a traditional, non-linear measure known as its ...

  6. Flow plasticity theory - Wikipedia

    en.wikipedia.org/wiki/Flow_plasticity_theory

    Plastic deformation of a thin metal sheet. Flow plasticity is a solid mechanics theory that is used to describe the plastic behavior of materials. [1] Flow plasticity theories are characterized by the assumption that a flow rule exists that can be used to determine the amount of plastic deformation in the material.

    en.wikipedia.org/wiki/Drawing_(manufacturing)

    Plastic drawing, sometimes referred to as cold drawing, is the same process as used on metal bars, applied to plastics. [8] Plastic drawing is primarily used in manufacturing plastic fibers . The process was discovered by Julian W. Hill in 1930 while trying to make fibers from an early polyester .
