WebOct 25, 2001 · Softer alloys, such as 3003 or 5052, can be bent about the same as mild steel. Stiffer materials, like 6061 or 2024, may require four to eight times the material thickness for the minimum inside radius. When sheet metal makes a transition from a bend to a flat surface, or to another bend, it tends to rip and tear.

WebTearing of material accompanied by appreciable gross plastic deformation and exhibit necking. The term ‘brittle fracture’ is used when a part is overloaded and breaks with no visible distortion and little or no plastic deformation. Here, a crack will form: • with little or no necking • without gross plastic deformation • WebBend Radius - As a rule, inside bend radius should be equal to material thickness. When the radius is less than recommended, this can cause material flow problems in soft material and fracturing in hard material. Bend Relief - When a bend is made close to an edge the material may tear unless bend relief is given. Figure "A" shows a torn part.

From … Tearing is the act of breaking apart a material by force, without the aid of a cutting tool. A tear in a piece of paper, fabric, or some other similar object may be the result of the intentional effort with one's bare hands, or be accidental. Unlike a cut, which is generally on a straight or patterned line controlled by a tool such as scissors, a tear is generally uneven and, for the most part, unplanned. An e…
WebTear strength used to characterize the tear resistance is one of the important mechanical parameters of rubber products. It is the value of force needed to rip a material and to make the crack continue until it fails. Therefore, it is calculated by force versus thickness: Tear strength = F/t. The nature of a tear depends on the way the force is ...
