- Title
Modulus of Elasticity.
- Abstract
The article reports that the modulus of elasticity of a material can be measured using a tensile test. The initial linear behavior of the stress-strain curve defines the elastic or recoverable strain region of a tensile test. The proportionality of stress and elastic strain in this region defines the elastic modulus by law of mathematician Robert Hooke. Most metals exhibit clear linear elastic regions. However, some materials such as gray cast iron do not. The various classes of gray cast iron must be evaluated for modulus by a modified method that involves the secant modulus or the tangent modulus.
