实施材料断裂时间的缺口拉伸试验的试验方法

Standard Test Methods for Conducting Time-for-Rupture Notch Tension Tests of Materials

适用范围:<p>Rupture life of notched specimens is an indication of the ability of a material to deform locally without cracking under multi-axial stress conditions, thereby redistributing stresses around a stress concentrator.</p> <p>The notch test is used principally as a qualitative tool in comparing the suitability of materials for designs that will contain deliberate or accidental stress concentrators.</p><p id="s00002">1.1 These test methods cover the determination of the time for rupture of notched specimens under conditions of constant load and temperature. These test methods also includes the essential requirements for testing equipment.</p> <p id="s00003">1.2 The values stated in inch-pound units are to be regarded as the standard. The units in parentheses are for information only.</p> <p id="s00004">1.3 <span class="italic">This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.</span>
