DEMONSTRATIONS OF IMPERFECTIONS - Coil

7 #15 Dishing —a coil with a wall that tapers toward one side instead of being perpendicular to the coil ID. Normally this occurs toward the end of large coils. Edge bead, edge build up —an excessive build up of paint on the edge of the strip. Fish eye —a round or elongated crater-type coating imperfection that may have a particle in the center.

Stretch Forming: Steps Stretch Forming:

Stretch Forming Sheet metal is stretched and simultaneously bent to achieve shape change (1) start of process (2) die is pressed into the work with force Fdie, causing it to be stretched and bent. F = stretching force • The shape is produced entirely by tensile stretching so the limiting strain is that at

A very small amount of deformation will occur at first (first stage). Then that metal bar will begin to stretch, but very, very slowly. It will keep on stretching for hours, weeks, maybe years, until it finally breaks in two. All this, when it wasn’t even loaded up to the yield strength (as measured by a short-time tensile test).
