The modulus of elasticity<\/strong> is a material parameter from materials engineering and defines the slope of the graph in the stress-strain diagram. This characteristic describes the relationship between tension<\/a> and strain<\/a> in the deformation of a solid body in a linear-elastic behavior. The modulus of elasticity is among the abbreviations Modulus of elasticity<\/strong> or as a formula symbol E.<\/strong> in the Spring calculation<\/a> known; it has the unit “N \/ mm\u00b2” of mechanical stress.<\/p>\n

The more resistance a material opposes its elastic deformation, the greater the amount of the Modulus of elasticity<\/a> . A component made of a material with a high modulus of elasticity (for example spring steel) is thus stiffer than a component of the same construction (with identical geometric dimensions) made of a material with a low modulus of elasticity (for example rubber). The modulus of elasticity is the constant of proportionality in Hooke’s law<\/a> .<\/p>\n

The definition of the modulus of elasticity: The modulus of elasticity is the slope of the graph in the stress-strain diagram with uniaxial loading within the linear elasticity range. This linear area is also called Hooke’s straight line<\/a> .<\/em><\/p>\n

\u03c3 = F \/ A (= force \/ area) die mechanical tension<\/a> ( Normal stress<\/a> , Not Shear stress<\/a> ) and \u0190 = \u2206L \/ L0 the expansion. The expansion is the ratio of the change in length \u2206L = L – L0 to the original length L0<\/p>\n

There is that here modulus of elasticity<\/a> for spring calculation at room temperature (20 \u00b0 C) for the most important spring materials.<\/p>\n

However, the modulus of elasticity is not constant with regard to all physical quantities. So also influence the different environmental influences, such as temperature<\/a> or Humidity<\/a> , the modulus of elasticity. The adjustment of the modulus of elasticity is determined at higher temperatures using the following formula, where the Spring material parameters<\/a> serve as a basis at room temperature (20 \u00b0 C).<\/p>\n
