Neutral Line Sheet Metal

The location of the neutral axis varies and is based on the material s physical properties and its thickness.

Neutral line sheet metal.

The line where the transition from compression to stretching occurs is called the neutral axis. The neutral line also called the neutral axis is an imaginary line that can be drawn through a cross section of the workpiece that represents the locus where no tensile nor compressive stresses are present on the work. K factor the location of the neutral axis in the material calculated as the ratio of the distance of the neutral axis t to the material thickness t. Notice how the sheet has thinned at the bend.

This thinning of the bend area moves the neutral line of the metal in towards the radius center. When metal is bent the top section is going to undergo compression and the bottom section will be stretched. The neutral line is an imaginary line that passes somewhere close to the middle of the material. The neutral axis position depends on the bend angle inside bend radius and method of forming.

It is the area where the material neither stretches nor compresses in the bend. Industrial metal supply sun valley ca is conveniently off the 5 freeway in the greater los angeles area just minutes north of burbank california. Figure 2 after bending the bend area is 10 to 15 percent thinner than before bending. This is not only our largest facility which includes a store and more than a football field sized warehouse full of product and processing capabilities as well as the company s corporate.

The neutral axis s behavior is the main reason the flat part needs to be smaller than the total of the formed piece s outside dimensions. If the material did not stretch at all then the neutral line would be at 50 of the material. Look closely a figure 1. Neutral axis the location in the sheet that is neither stretched nor compressed and therefore remains at a constant length.
