用于制造弹性敏感元件的轧制弹性薄带,根据材料拉伸时的变形功概念,应满足σ_e~2/E=最大 (1)这个比值,表征单位体积材料的弹性储能能力。类似的表达方式还有σ_(0.2)/σ_b、σ_(0.002)/E 等。各种材料的弹性模量,大体是一个不敏感的物理量。因此,在实际生产中,总是努力提高弹性极限,使材料具有较高的弹性储能能力。测量材料的这些性能,是评价弹性材料质量优劣的一个重要方面,过去几年中,精密合金
The elastic strip used to manufacture the elastic sensing element should meet the ratio of σ_e ~ 2 / E = max (1) according to the concept of work of deformation when the material is stretched to characterize the elastic energy storage capacity per unit volume of material. Similar expressions also σ_ (0.2) / σ_b, σ_ (0.002) / E and so on. The elastic modulus of various materials, in general, is an insensitive physical quantity. Therefore, in actual production, always strive to improve the elastic limit, so that the material has a high elastic energy storage capacity. Measurement of these properties of materials is to evaluate the quality of elastic material is an important aspect of the past few years, precision alloys
