测量杨氏模量实验方法的探讨

Discussion on the experimental method of measuring Young's modulus

杨氏模量(Young’s modulus)是表征在弹性限度内物质材料抗拉或抗压的物理量,它是沿纵向的弹性模量。根据胡克定律,在物体的弹性限度内,应力与应变成正比,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,仅取决于材料本身的物理性质。

Young's modulus(Young's, modulus) is a physical quantity that represents the tensile or compressive properties of a material in an elastic limit. It is the modulus of elasticity along the longitudinal direction. According to Hooke's law, the objects within the elastic limit, stress is proportional to the ratio, known as the young's modulus, it is a physical quantity to describe the material properties and physical properties depend only on the material itself.
