一种测定橡胶杨氏模量的方法

A Measuring Method on Young Modulus of Rubber

大学物理测量金属杨氏模量实验通常采用拉伸法和梁弯曲法，但是该种方法在进行实验的过程中存在设备难以调节，读数存在误差，实验的成本较高等缺点．而且该设备对测量非金属的杨氏模量无法操作．为了使该实验问题具体化，实验仪器简单化，实验现象明显可靠，本文介绍了一种测量非金属杨氏模量的简易实验装置．

We in college often measure Young Modulus of metvcals by tensile method or bending beam method with disadvantages including difficulties in regulating apparatus, reading error and high cost. What＇s more, its apparatus cannot be applied into measuring that of nonmetal. To specific the experiment, simplify the equipmen and make phenomenon more clear, this essay introduce a kind of simple apparatus to measure Young modulus of nonmetal.
