2 Methods of stressing U-bend specimens
Covers procedures for designing, preparing and using U-bend test specimens for investigating the susceptibility of a metal to stress corrosion. U-bend specimens may be used to test a variety of product forms. They are used for sheet, plate or flat extruded material, which conveniently provides flat specimens of rectangular cross-section, but may be employed for wire or rod, or for machined specimens of circular cross-section. Can be used for parts joined by welding. The U-bend test is used to establish whether a metal is susceptible to stress corrosion cracking in a given environment.
