  2. Bending (metalworking) - Wikipedia

    en.wikipedia.org/wiki/Bending_(metalworking)

    K-factor is a ratio of the location of the neutral line to the material thickness as defined by t/T where t = location of the neutral line and T = material thickness. The K-factor formula does not take the forming stresses into account but is simply a geometric calculation of the location of the neutral line after the forces are applied and is ...

  3. K-factor (metallurgy) - Wikipedia

    en.wikipedia.org/wiki/K-factor_(metallurgy)

    The K-factor is the bending capacity of sheet metal, and by extension the forumulae used to calculate this. [1] [2] [3] Mathematically it is an engineering aspect of geometry. [4] Such is its intricacy in precision sheet metal bending [5] (with press brakes in particular) that its proper application in engineering has been termed an art. [4] [5]

  4. Neutral axis - Wikipedia

    en.wikipedia.org/wiki/Neutral_axis

    The neutral axis is an axis in the cross section of a beam (a member resisting bending) or shaft along which there are no longitudinal stresses or strains. Theory

  5. K-factor - Wikipedia

    en.wikipedia.org/wiki/K-factor

    K-factor (Elo rating system), a constant used in Elo rating system; K-factor (marketing), the growth rate of websites, apps, or a customer base; K-factor (sheet metal), the ratio of location of the neutral line to the material thickness; The K Factor, a fictional TV show within Harry Hill's TV Burp; Bondi k-factor, the "k" in Bondi k-calculus

  6. Neutral plane - Wikipedia

    en.wikipedia.org/wiki/Neutral_plane

    An evenly loaded beam, bending (sagging) under load. The neutral plane is shown by the dotted line. In mechanics, the neutral plane or neutral surface is a conceptual plane within a beam or cantilever. When loaded by a bending force, the beam bends so that the inner surface is in compression and the outer surface is in tension.

  7. Sheet metal forming analysis - Wikipedia

    en.wikipedia.org/wiki/Sheet_metal_forming_analysis

    For sheet metal forming analysis within the metal forming process, a successful technique requires a non-contact optical 3D deformation measuring system. The system analyzes, calculates and documents deformations of sheet metal parts, for example. It provides the 3D coordinates of the component's surface as well as the distribution of major and ...

  8. Forming (metalworking) - Wikipedia

    en.wikipedia.org/wiki/Forming_(metalworking)

    In metalworking, forming is the fashioning of metal parts and objects through mechanical deformation; the workpiece is reshaped without adding or removing material, and its mass remains unchanged. [1] Forming operates on the materials science principle of plastic deformation, where the physical shape of a material is permanently deformed.

  9. Forming limit diagram - Wikipedia

    en.wikipedia.org/wiki/Forming_limit_diagram

    A forming limit diagram, also known as a forming limit curve, is used in sheet metal forming for predicting forming behavior of sheet metal. [1] [2] The diagram attempts to provide a graphical description of material failure tests, such as a punched dome test. In order to determine whether a given region has failed, a mechanical test is performed.
