适用范围：Covers procedures for designing, preparing and using U-bend test specimens. These specimens may be used to test a variety of product forms (for example sheet, plate, flat extruded material, wire or rod). The principal acvantages of the U-bend test are its simplicity and its adaptability for use in plants. A disadvantage is that stesses cannot be quantified with accuracy. U-bend specimens made from high strength materials may fracture rapidly and can be dangerous.
