It is physically tougher to control distortion in a square tube than a round tube. These forces behave in a certain way to draw in the vertical edges of the tube distorting the cross section into a concave shape. Square tube material on the inside of the bend surface has a tendency to expand vertically and flow horizontally along the tube face. Round tube allows metal to flow evenly in all directions during the bend which makes it easier to control distortion. This makes the square tube more susceptible to distortion. Very often, accessories, such as swords and guns which are usually long, slender shapes molded out of a slightly softer plastic than the figures, will also suffer greatly from bending. Updated paths and strokes workflow Streamlined complex & organic shape workflow.
FLEXISIGN 12 BEND SHAPE GENERATOR
In square tubing the entire tube wall is parallel to this plane and so is exposed to the tensile and compressive stress at the outside and inside of the bend. Collectors often find bent parts on an action figure around the thinner areas of the toy, such as the ankles or wrists. QR Code generator More effect like Bridge Warp, Drop Shadow. The plane of highest tension or compression is tangent to the cross section so it is less prone to distortion. Round tubing has less material in the most highly stressed regions. In tube bending you can bend round or square tubing. If the ultimate compressive strength of the material is reached, the tube will experience localized buckling resulting in rippling of the inside bend surface. The wall thickness on the inside of the tube bend will thicken due to compressive stresses. If the ultimate tensile stress of the material is surpassed, then the tube will rip along the outer bend surface. Wall thickness on the outside cross section of the bend will thin-out due to tensile stresses, because the outer wall tends to be pulled in toward the centerline or neutral axis of the part. When a metal tube is bent, the cross section material fibers experience tension on the outside of the bend area and compression on the inside of the bend area.
