Elastic modulus measures the resistance of the material to elastic—or “springy”—deformation. Low modulus materials are floppy and stretch a lot when they are pulled (squash down a lot when pushed). High modulus materials are opposite—they stretch very little when pulled (squash down very little when pushed).
What Does High Elastic Modulus Mean?
An elastic modulus (also known as a modulus of elasticity) is a number that measures an object‘s resistance to being deformed elastically (i.e., non–permanently) when a force is applied to it.
The elastic modulus of a material is determined by the force required to produce a small, but measurable, deformation in the material.
The elastic modulus is a fundamental property that is used to characterize the mechanical behavior of materials. The elastic modulus of a material is usually represented by the letter E.
The units of elastic modulus are typically gigapascals (GPa) or newtons per square meter (N/m2). The value of elastic modulus can vary depending on the type of material, as well as the temperature and strain rate at which the material is being tested.
Elastic modulus is an important property because it is used to calculate the deformation of a material under an applied load. The deformation of a material is directly related to the elastic modulus and the applied load.
For example, a material with a high elastic modulus will deform less than a material with a low elastic modulus when the same load is applied.
