Elastic deformation is reversible, meaning that the material returns to its original shape after the load is removed. See more Young's modulus E, can be calculated by dividing the tensile stress, $${\displaystyle \sigma (\varepsilon )}$$, by the engineering extensional strain See more • Bending stiffness • Deflection • Deformation • Flexural modulus See more Material stiffness should not be confused with these properties: • Strength: maximum amount of stress that material can withstand while staying in the elastic (reversible) … See more Young's modulus enables the calculation of the change in the dimension of a bar made of an isotropic elastic material under tensile or compressive loads. For instance, it predicts how much a material sample extends under tension or shortens under compression. The … See more • ASTM E 111, "Standard Test Method for Young's Modulus, Tangent Modulus, and Chord Modulus" • The ASM Handbook (various volumes) … See more WebMay 26, 2024 · We know that the Young's modulus of elasticity ( Y) is given by: Y = F L A Δ L where F is the tensile force, L is the length of the material, A is the area of cross section and Δ L is the extension due to the applied …

Do metals generally have larger values of Young
WebMar 23, 2024 · Some materials have no elastic range, others move from elastic to plastic or brittle behavior very quickly, whereas others have a clearly defined elastic range before an internal process of atomic displacement begins a plastic phase. Examples of Young’s modulus values (in gigapascals, GPa) are: ABS (1.4–3.1 GPa), aluminum (69 GPa), and ... WebYoung’s modulus, E = Young’s Modulus Most engineering materials are linear elastic: under uniaxial load, a sample of constant cross -section extends in proportion to the load (Hooke’s Law). By converting load to stress, and extension to strain: - the response is made independent of geometry; - the slope is then a material property, Young ...
