精选优质文档-倾情为你奉上杨氏模量的测量大学物理实验论文摘要:物体受外力作用时要发生形变,只要外力不超过一定限度,则作用力和相应形变之间将遵循胡克定律。根据,在物体的内,与应变成正比,比值被称为材料的杨氏模量,它是表征材料性质的一个物理量。杨氏模量测试方法一般有静态法和动态法,静态法包括拉伸法、扭转法和弯曲法,动态法包括弯曲共振法、横向共振法、扭转共振法。关键词:杨氏模量 拉伸法 弯曲共振法Measurement of Youngs modulus Abstract: The object to be deformed by external force, as long as the external force does not exceed a certain limit, then force of action and corresponding deformation will follow the Hookes law . According to Hookes law, the object within the elastic
