Since elongation is dimensionless, modulus has the units of stress. The relevant ASTM test is D 638. In contrast to structural metals such as mild steel, the stress-strain graphs for many plastics exhibit some curvature, even at very low strains. Since there is then no significant linear ...
The modulus of elasticity of stainless steel orthodontic wires was found to be 20% below the normally assumed range of 19.3 to 20.0 x 10(4) MPa (28.0 to 29.0 x 10(6) psi). Use of the latter value can result in significant computational errors in orthodontic applicance mechanics. The ...

Metals and Alloys - Young's 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 ...
lb.); 𝐸E is the modulus of elasticity of steel (MPa, psipsi) = 210,000 MPa0,000 MPa, 30 ×× 106 psi; 𝐼I is the moment of inertia of rail (mm4, in4mm4, in4) = 36,700,000 mm4 mm4, 88.2 in4 in4 (132RE Rail); 𝐸𝐼EI is the flexural rigidity of the rail....
Young’s Modulus (Elastic Modulus) of various materials, including metals, plastics, and composites. How stiffness and elasticity influence material performance in engineering applications.
The elasticity of steel and other metals arises from short-range interatomic forces that, when the material is unstressed, maintain the atoms in regular patterns. Under stress the atomic bonding can be broken at quite small deformations. By contrast, at the microscopic level, rubberlike materials ...
An elastic modulus, or modulus of elasticity, is the mathematical description of an object or substance’s tendency to be deformed elastically (i.e., nonpermanently) when a force is applied to it. From: Encyclopedia of Biomedical Engineering, 2019 ...
