Young’s modulus (E) is defined as the ratio of the stress applied to the material along the longitudinal axis of the specimen tested and the deformation or strain, measured on that same axis. Young’s Modulus is also known as tensile modulus, elastic modulus or modulus of elasticity.

Elastic properties and Young's modulus for metals and alloys like cast iron, carbon steel and more. It is convenient to express the elasticity of a material with the ratio stress to strain, a parameter also termed as the tensile elastic modulus or Young's modulus of the material - usually with the symbol - E. Young's modulus E describes the material's strain response to uniaxial stress in the direction of this stress (like pulling on the ends of a wire or putting a weight on top of a column, with the wire getting longer and the column losing height), Average Young's modulus values of wood along the longitudinal axis (E L) obtained from bending tests are given in the following table. Average coefficients of variation of E L is 22% based on results of bending tests of clear & green wood from approximately 50 species. Två tal a och b är kongruenta modulo n om de ger samma rest vid division med n (a,b och n är heltal, n är större eller lika med 2). Detta betecknas ≡ (). Man kan också skriva ≡.

Den elastiska modulen, även känd som elasticitetsmodulen eller Youngs modul, är i huvudsak en mätning av styvheten hos The shear resistance of any thread can be calculated by following E.M. Alexander's method1, depending on four main parameters: The Young modulus E of the Youngs modul - Young's modulus. Från Wikipedia Youngs modul är lutningen för den linjära delen av stress-töjningskurvan.

Slope of the stress-strain diagram within the elastic zone is called “Modulus of Elasticity” or “Young's Modulus”.

This video introduces and explains stress, strain and Young's modulus.When revising for your exams it may seem like you are under stress and strain, however, 1.1 This test method covers the determination of Young's modulus, tangent modulus, and chord modulus of structural materials, see Fig. 1. This test method is limited to materials in which and to temperatures and stresses at which creep is negligible compared to the strain produced immediately upon loading and to elastic behavior.

Mohan Prasad Selvaraj. The elastic moduli, Young’s modulus E, and shear modulus G, describing the linearity between stress and strain in the elastic regime, differ a great deal for different material classes, composition, orientation, and temperature (Fig. 1).In particular, advanced high-temperature materials such as monocrystalline (SX) and directionally solidified (DS) nickel-base alloys show a clear orientation Michelle gave a great summary on the qualitative relationship between hardness (H), elastic modulus (E), and yield strength (Y).In fact, it has been a long history to find this relation, and it is still an on-going topic.
