The roasting test and bend test results .

This paper firstly expatiates the object and purpose of the bend test during the welding procedure qualification.

Through the comparison between the outdated and the lastest standards it is found that althongh the years for preparation of two standards are different,bath for equivalent to the international standard ISO 7438:1985 “metallic materials-bend test” the definite answer has not found out for some questions.

Metal material bending test is an important item when raw materials come to factory in boiler and pressure vessel manufacturing trade.

Low-temperature bending tests of asphalt mixture under-10℃ have been done by MTS810 material test system.

In order to promote the industrialization of the FRP fishing boat, the writers consulted a lot of material in our country and abroad, conduct ed bending tests for some slices of FRP ship s bulk, and then bring forward rule s for this kind of test.

Analysis of the reasons for presence of cracks on the test samples taken from the witness welded products during the root bend test as well as measures to be adopted;

Research on the Bending Experiment Method on Copper and Cuprum Alloy Contact Wires for Electrified Railways;

Bending experimented test system of piston rod based on virtual instruments

Several experiment methods on the adhesion property between CFRP and concrete are studied and analyzed,of these methods,bending experiment method is easy and very effective.
