一、前言本方法是为了满足生产的急需和弥补现有杨氏模量测试方法不足而提出的。现有的悬丝耦合横振动法适用大尺寸样品,而用微型拉伸试验机又仅能测量极细的丝材的杨氏模量。当样品的直径或厚度为0.1毫米左右时,这二种方法都不太有效。本方法初步解决了这个范围内金属丝材和片材的杨氏模量的测试问题。然而由于时间所限,目前只完成室温及空气气氛下的测试工作,而高温及真空条件下的测试工作尚待今后进行。再者 First, the preface This method is to meet the urgent need of production and to make up for the lack of the existing Young's modulus test method. The existing method of transverse coupling vibration of the suspension wire is suitable for large-size samples, and the micro-tensile testing machine can only measure the Young's modulus of the very thin wire. When the sample diameter or thickness of about 0.1 mm, these two methods are not very effective. The method initially solves the problem of testing the Young's modulus of metal wire and sheet in this range. However, as the time limit, only the test work under room temperature and air atmosphere is completed at present, while the test work under high temperature and vacuum is yet to be carried out in the future.
