modulus of elasticity
The 'modulus of elasticity' is also known as 'Young's modulus' or 'elastic modulus' and is crucial in understanding a material's ability to withstand deformation.

Definition
C1Physics
(technical, academic)A measure of a material's resistance to elastic deformation, defined as the ratio of stress to strain.
Example
- Steel has a high modulus of elasticity, making it very stiff and resistant to deformation.
- When calculating the modulus of elasticity, engineers use the initial linear portion of the stress-strain curve.
C1Engineering
(technical, academic)The ratio of applied stress to resulting strain within the elastic deformation range, indicating material stiffness.
Example
- The modulus of elasticity is essential for determining how much a material will deform under load.
- Materials with a high modulus of elasticity are preferred in construction for their ability to maintain shape under stress.
C1Materials Science
(technical, academic)A property that quantifies a material's stiffness by measuring the relationship between stress and strain in the elastic region.
Example
- Polymers typically have a lower modulus of elasticity compared to metals.
- Understanding the modulus of elasticity helps in selecting materials for specific applications.
