Neutral Axis In Sheet Metal

The granular bonds are stretched pulled and sometimes break forcing the grains apart as they come under tensional stresses.

Neutral axis in sheet metal.

In sheet metal the k factor is the ratio of the neutral axis to the material thickness. K factor k can be defined as follows. But add a little stress and force the metal to bend and watch what happens. The k factor in sheet metal working is the ratio of the neutral axis to the material thickness.

K factor a constant determined by dividing the thickness of the sheet by the location of the neutral axis which is the part of sheet metal that does not change length. K factor in sheet metal bending is a constant used to calculate sheet metal flat length or flat pattern. When the sheet is flat without any applied stress the neutral axis is in the middle of the sheet. The bend allowance and bend deduction are two measures that relate the bent length of a piece of sheet metal to the flat length.

The line where the transition from compression to stretching occurs is called the neutral axis. Mathematically k factor value is equal to the ratio of position of neutral axis and sheet thickness. When metal is bent the top section is going to undergo compression and the bottom section will be stretched. The line where the transition from compression to stretching occurs is called the neutral axis.

When a piece of metal is being formed the inner portion of the bend compresses while the outer portion expands see figure 1. K factor is a ratio that represents the location of the neutral axis with respect to the thickness of the sheet metal part and depends on material thickness and bend radius. The k factor in sheet metal working is the ratio of the neutral axis to the material thickness. When metal is bent the top section is going to undergo compression and the bottom section will be stretched.

The location of the neutral axis for a specific sheet is defined by a factor called k factor.
