E = stress / strain =σ / ε = (Fn/ A) / (dl / lo) (4) where E =Young's Modulus(N/m2) (lb/in2, psi) Modulus of Elasticity, or Young's Modulus, is commonly used for metals and metal alloys and expressed in terms106lbf/in2, N/m2or Pa. Tensile modulus is often used fo...
一个是应力(stress),应力是等于拉力除以横截面积,这样就是单位面积的受力了; 另外一个是伸长比例(strain),等于伸长长度除以原始长度,即伸长的百分比。 由于stress已经去除掉了面积的干扰因素,strain去除掉了原始长度的干扰因素,我们对杨氏模量的定义即为: 杨氏模量是只和材料相关的物理量,其数值越大,说明在变形的时...
Young's modulus assess how a polymer responds to external forces. See typical stiffness values for various plastics to guide your material selection.
Young's modulus（杨氏模数）弹性模数，杨氏棱镜，弹性模量如有疑问，请追问!杨氏模量等于stress除以strain,杨氏模量大的材料不容易形变，和spring constant 相似的意思杨氏模量
a convenient parameter is the ratio of the stress to the strain, a parameter called the"Young's modulus" or "Modulus of Elasticity" of the material. Young's modulus can be used to predict theelongation or compression of an object as long as the stress is less than the yield strength of...
Young's modulus is a measure of the elasticity or extension of a material when it's in the form of a stress–strain diagram. It is named after Thomas Young.
Young's modulus is defined as the ratio of stress below the proportional limit to the corresponding strain. It is a measure of the rigidity or stiffness of a material. In terms of the stress-strain curve, Young's modulus is the slope of the stress-strain curve in the range of linear pr...
The Young modulus is the slope of the Stress-Strain linear regression, which in this case is 3.39 * 10^4 bar (or 3.39 GPa). Note that by this linear regression is performed using the whole strain range (from 0 to 0.1). Following Ref. [1], we will now show how to compute the Yo...
Elastic modulus is a general term for the ratio of stress to strain in materials, while Young's modulus specifically measures this ratio for linear elastic deformation under tension or compression.
