现代材料试验方法用于检验制成规范的标准机械性能,获取强度计算所需要的特性,以及可以进行材料机械性质的科学研究。由于科学研究的需要,对试验装置和测量装置提出更高的要求,并且研究获得的特性成了最重要的结构计算所必需的原始数据,然后才逐渐成为在实验室条件下必须测定的材料标准规范。因此,应从所指出的计算和试验方法的发展过程
Modern materials testing methods are used to test the standard mechanical properties that are made into specifications, to obtain the properties required for strength calculations, and to conduct scientific research on the mechanical properties of materials. Due to the need of scientific research, higher requirements are placed on the test apparatus and measuring apparatus, and the characteristics obtained from the study become the most important raw data necessary for structural calculation before gradually becoming the material standard that must be determined under laboratory conditions specification. Therefore, it should be pointed out that the development of calculation and test methods
