Bending Force and Spring-Back in V-Die-Bending of Perforated Sheet-Metal Components Using VIKOR Method

Sheet metal can be made from different metals, including tin, nickel, steel, copper, brass, zinc, and chrome. Silver, gold, and palladium (which is also employed as a catalyst) are among significant sheet metals for aesthetic purposes. When force exerted to a sheet of metal, the materials is elastically deformed and its geometric is changed without any substance being removed. This is known as sheet metal shaping. In the sheet metal formation process, a metal is reshaped while it is still solid. Some metals' plasticity allows for the deformation of a solid piece of metal into a desirable shape without compromising mechanical integrity. Cutting, striking, folding, and welding flat pieces of steel or copper into metal structure or goods is known as sheet metal manufacturing. Almost any shape can be created by cutting, bending, or stretching sheet metal; this is typically accomplished by heating the metal. Alternative Taken as Thickness, Yield Strength, Ultimate tensile, Maximum elongation. Assessment option The cold-rolled materials used consisted of an electro-galvanized draw quality special killed steel of two different thickness (EGCR3, EGCR3- 2), hot dipped galvanized draw quality special killed steel (HDGCR3), carbon sheet Chrysler Spec MS-steel (CRDSTB), electro-galvanized-annealed high strength steel (HSGS25S), a generic carbon steel (EG250B). from the result is based on EGCR3-2 are the result seen and got the first Rank, whereas the EG250B got having the lowest rank. The Value of dataset for sheet metal components in VIKOR method shows that it results in EGCR3-2 and top ranking
