| 金属材料的杨氏模量反映了应力-应变关系中的线性刚性系数，有助于结构稳定性的分析和新材料的研发。多阶谐振法测量金属材料的杨氏模量，其应变比静态方法小，结果更加精确。根据欧拉-伯努利梁理论在基本弯曲共振角度的推导，提出了一种基于多阶谐振动态测量杨氏模量的方法。针对四种金属材料进行测试与计算，验证本方法的精准性和一致性。 |
| 英文摘要: |
| The Young's modulus of metallic materials reflects the linear stiffness coefficient in the stress-strain relationship, which helps in the analysis of structural stability and the development of new materials. The multistep resonance method was used to measure the Young's modulus of metallic materials with smaller strain than the static method, and the results are more accurate. Based on the derivation of Euler-Bernoulli beam theory at the fundamental bending resonance angle, a method based on the dynamic measurement of Young's modulus by multi-order resonance was proposed. Tests and calculations were carried out for four metallic materials to verify the accuracy and consistency of this method. |
