Engineering Analysis of Bending
{"Image DocumentName": "Engineering Analysis of Bending", "Image ImageDescription": "Bending radius R is normally specified on the inside of the part, rather than at the neutral axis. The bending radius is determined by the radius on the tooling used for bending. Bending Allowance: If the bend radius is small relative to sheet thickness, the metal tends to stretch during bending. Knowledge about Stretching is important to have final part length according to specified dimensions. It is about determining the length of neutral axis before bending, in accordance with final bend length. The bend allowance (BA) is the length of the arc of the neutral line between the tangent points of a bend in any material. BA = 2pA(R + Kbat)/360. Where BA \u2013 bend allowance(mm); A - bend angle, degrees; R \u2013 bend radius, in. (mm); t \u2013 sheet thickness; and. Kba - factor to estimate stretching. if R < 2t, Kba = 0.33; and if R>=2t, Kba =0.5.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
