Definition, Meaning & Synonyms
modulus of elasticity
noun
ˈmɒd.jʊ.ləs əv ɪˈlæs.tɪ.sɪ.ti
Definition
The modulus of elasticity is a measure of a material’s ability to deform elastically (i.e., non-permanently) when a force is applied. It quantifies the relationship between stress (force per unit area) and strain (deformation) in a material.
Examples
- The modulus of elasticity for steel is much higher than that for rubber.
- Engineers calculate the modulus of elasticity to predict how materials will behave under different loads.
- Wood has a lower modulus of elasticity compared to metals, allowing it to bend more easily.
Meaning
In simpler terms, the modulus of elasticity indicates how stiff a material is. A higher modulus means the material is less likely to deform, while a lower modulus means it can bend or stretch more easily under stress.
Synonyms
- Elastic modulus
- Young’s modulus (specific to tensile elasticity)
- Shear modulus (for shear elasticity)
- Bulk modulus (for volumetric elasticity)
