Bend Testing
Bend testing is a procedure to determine the relative ductility of metal that is to be formed (usually sheet, strip, plate or wire) or to determine soundness and toughness of metal (after welding, etc.) The specimen is usually bent over a specified diameter mandrel. The four general types of bends are; free bend, guided bend (ASTM E190), semi-guided bend (ASTM E290), and wrap around bend.
A bending test, also known as a bend test, is used to determine the strength of a material by applying force to the item in question and seeing how it reacts under pressure. Typically the bend test measures ductility, the ability of a material to change form under pressure and keep that form permanently.
In certain cases the bending test can determine tensile strength. When using the bend test for this purpose, testers examine which side of the material breaks first to see what type of strength the material has. It also lets them know what kinds of pressure it holds up against and what kinds it doesn't.
Ductility describes how well a material, usually metal, can be stretched and keep its new shape. Steel, for example, is highly ductile. If pressure is applied that stretches the steel into a new shape, it will keep this shape even after the pressure has been removed. This characteristic is referred to as ductility is a desirable characteristic for metals and other building material.
To determine how ductile a material is, a bending test is used. Force is applied to a piece of the material at a specific angle and for a specific amount of time. The material is then bent to a certain diameter using force. After the bending test is over, the material is examined to see how well it held its shape once the pressure was removed, and whether or not the material cracked when pressure was applied.
This test can also determine tensile strength. The test may be used when more brittle materials need to be tested. These brittle materials may not hold up well under a normal test for tensile strength, therefore a bending test is used. It is applied the same way as normal, by bending the material while applying force, and then the results are examined. If the material shows cracks on the bent side, this shows the material holds up better against compression than tension
