A test of ductility by bending or folding, usually with steadily applied forces. In some instances the test may involve blows to a specimen having a cross section that is essentially uniform over a length several times as great as the largest dimension of the cross section.
Bending tests are carried out to ensure that a metal has sufficient ductility to stand bending without fracturing. A standard specimen is bent through a specified arc and in the case of strip, the direction of grain flow is noted and whether the bend is with or across the grain.
a standard test done on reinforcing steel bars to check its amenability to bending in structural applications
Method for measuring ductility of certain materials. There are no standardised terms for reporting bend test results for broad classes of materials; rather, terms associated with bend tests apply to specific forms or types of materials.
A test commonly made by bending a cold sample of specified size through a specified circular angle. Bend tests provide an indication of the ductility of the sample.
A test for determining relative ductility of wire that is to be formed, and for determining soundness and toughness of wire. The specimen is usually bent over a specified diameter through a specified angle for a specified number of cycles.
A test that determines the toughness of a metal through bending.
A test in which wire is bent over a specified diameter through a certain angle and for a preset number of cycles, in order to determine its relative ductility, soundness and toughness.
A test that is used to determine the ductility and malleability of various metals.
A form of mechanical testing used to assess the ductility of a piece of steel. In carrying out such a test it will often be necessary to follow a detailed procedure which may cover the form, selection and preparation of the test specimen and exactly how the specimen is to be bent and the result assessed and reported, eg see BS1639: 1964. The results are normally expressed as a minimum bend diameter in the form nT, where n is a number (sometimes a decimal fraction), and T is the thickness of the steel.
