Pure bending is a condition of stress where a bending moment is applied to a beam without the simultaneous application of Cylinder stresses axial , Shear stress shear , or Deformation mechanics torsional forces . Pure bending is the flexure bending of a beam under a constant bending moment M therefore pure bending only occurs when the shear force V is equal to zero since dM dx V.

unreferenced date May 2009 A bending moment exists in a structural element when a Moment physics moment is applied to the element so that the element bends. Moments and torque s are measured as a force multiplied by a distance so they have as unit newton metre s N m , or pound foot torque pound foot or foot pound ft lb . The concept of bending moment is very important in engineering particularly in Civil engineering civil and mechanical engineering and physics . Tensile stresses and compressive stresses increase proportionally with bending moment, but are also dependent on the second moment of area of the cross section of the structural element. Failure in bending will occur when the bending moment is sufficient to induce tensile stresses greater than the Yield engineering yield stress of the material throughout the entire cross section. It is possible that failure of a structural element in Shearing physics shear may occur before failure in bending, however the mechanics of failure in shear and in bending are different. The bending moment at a section through a structural element may ... each other and maintain a state of Dynamic equilibrium equilibrium so the same bending moment ... forces from one side to the other.

Unreferenced date February 2007 Plastic bending is a nonlinear behaviour peculiar to members made of ductile materials that frequently achieve much greater ultimate bending strength than indicated by a linear elastic bending analysis. In both the plastic and elastic bending analyses of a straight beam, it is assumed that the strain distribution is linear about the neutral axis plane sections remain plane . In an elastic analysis this assumption leads to a linear stress distribution but in a plastic analysis the resulting stress distribution is nonlinear and is dependent on the beam s material. The limiting plastic bending strength math M r math can generally be thought of as an upper limit to a beam s load carrying capability as it only represents the strength at a particular cross section and not the load carrying capability of the overall beam. A beam may fail due to global or local instability before math M r math is reached at any point on its length. Therefore, beams should also be checked for local buckling, local crippling, and global lateral torsional buckling modes of failure. Note that the deflections necessary to develop the stresses indicated in a plastic analysis are generally ....

Band bending refers to the local change in energy of electrons at a semiconductor junction due to space charge effects. Because the common way to visualize the electron energy state s and Fermi level in a material is to draw bands on an energy vs. distance plot, band bending refers to bending in these diagrams and not in any physical form. Band bending can occur at a material vacuum interface or when two materials with different local work function s are placed in contact. Some examples of situations where band bending is technologically relevant are through the doping one area of a semiconductor to create a p type semiconductor p type in contact with an n type semiconductor n type , say or metal induced gap states of a metal being affixed to a semiconductor . In general, bands will bend locally when materials come in contact, because the two Fermi level s of the materials will equilibrate to the same level through a local exchange of charge carriers in semiconductors charge carrier s either electron hole holes or electrons . This exchange of charge changes the energies of those charge carriers who have been exchanged, giving a curvature to the energy vs. distance diagram near the junction. Knowing how bands will bend when two different types of materials are brought in contact is key to understanding whether the junction will be rectifying Walter H. Schottky Schottky or ohmic contact ohmic . The degree of band bending depends on the relative Fermi levels and carrier concentrations of the materials forming the junction.

Heat bending is the procedure of bending thin sheets of wood into different curves and shapes using moisture and a bending iron. By placing the sheet of wood into water, the moisture and heat from the bending iron will reform the structure of the wood, reorganizing the fibers of the wood to prevent the wood from springing back to its original state ref http www.scavm.com awfribs.htm ref . This process is usually used for making sides or ribs for violin s, guitar s, mandolin s and other projects ref http www.stewmac.com freeinfo I 0689.html ref . Description Bending irons, though having an iron core, can have different types of metal casing depending on the type of material to be bent. For example, an aluminum cover is preferable for bending woods and plastics while a stainless steel cover is better for bending and shaping pipe and iron work. Bending irons are most commonly Electric heating electrically heated , therefore it is possible to control the heat output so as not to overheat the workpiece and change its chemical balance. The iron itself can be purchased in different shapes and sizes to better accommodate the needs of the operator. Some shapes include but not limited to teardrop, round, and oval. Process To properly bend a sheet of wood, there are a few techniques that will help. The hardness of the wood will determine how long is required to soak the wood in water. The harder the wood, the more time is needed to fully soak the wood, making it easier to bend and preventing the wood from springing back to its original form. Popular hardwoods are oak , maple , cherry , birch , walnut , Fraxinus ash and poplar . Common softwoods are pine , fir , spruce , hemlock, Cedar wood cedar and redwood ref http www.sawdustmaking.com Wood wood.html ref .

A cornice brake only allows for simple bends and creases, while a box and pan brake also allows one to form box and pan shapes. ref http www.irvansmith.com scart index.php?cPath 3 40 41&sort 3a&filter id 24 Box & Pan ref It is also known as a bending machine or bending brake . Description The brake consists of a flat surface onto which the material is placed, and a Clamp tool clamping bar which will come down and hold the material firmly during the bend. This clamping action may be manual, automatic or operated using a foot pedal. The front, gate like, plate of the machine is hinged and may be lifted, forcing the material extended over a straight edge to bend to follow the plate. The bends can be to any angle up to a practical limit of about 120 degree angle degree s, somewhat more in the case of a bar folder. If the area to be bent is narrow enough, a sharper bend e.g., for a hem can be made by inserting the bend under the clamping bar and lowering it. Cornice Brake A cornice brake has a solid clamping bar, the full width of the machine thus, it can only make straight bends, the entire width of the workpiece. Box and Pan Brake In a box and pan brake, the clamping bar includes several removable blocks, which may be removed and rearranged to permit bending of restricted areas of a piece of sheet metal or of already partially formed pieces. After bending, a box or pan form is then completed by screw , solder , welding weld , rivet , or other metal fixing process. Bar Folder This is a simplified brake, usually much smaller than cornice or box and pan brakes. Typically, a single handle both clamps the workpiece and makes the bend, in a single motion, but the depth is usually much less than what a cornice or box and pan brake can handle.
