标准范围

介绍U形弯曲试样的设计、制备和使用程序。这些试样可用于测试各种产品形式(例如板材、板材、扁平挤压材料、线材或棒材)。U形弯曲试验的主要优点是其简单性和适用于植物的适应性。缺点是不能准确地量化STESS。由高强度材料制成的U形弯曲试样可能会快速断裂,并且可能存在危险。

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.
