Enter the stress and strain acting on the material into the elasticity calculator. The calculator will return the Elastic Modulus of that material.

Elasticity Formula

The following formula is used to calculate the elastic modulus of a material.

E = Se/Sa
  • Where E is the elastic modulus
  • Sa is the strain
  • Se is the stress

It’s important to note that this is strain and stress in the same direction, i.e. axial.

Elasticity (Physics) Definition

Elasticity is a fundamental concept in physics that describes the property of materials to deform under the application of external forces and return to their original shape when the forces are removed. It measures how much a material can stretch or compress when subjected to stress.

When a force is applied to an object, it generates stress, causing the object to change its shape.

Elastic materials can absorb this stress and store potential energy. As a result, they can undergo temporary deformation while maintaining their original structure. Once the external force is removed, the stored energy is released, causing the material to return to its initial state.

In mechanics, the study of elastic materials helps in understanding the behavior of structures under different loads. Engineers rely on elasticity to design buildings, bridges, and other structures that can withstand external forces, such as wind, earthquakes, or heavy loads, without permanent deformation or failure.

How to calculate elasticity?

How to calculate elasticity

  1. First, measure the strain on an object

    Measure the strain on an object using proper instrumentation.

  2. Next, measure the stress on an object

    Using the same instrumentation/press, measure the stress on the object.

  3. Calculate the elastic modulus

    Calculator the elastic modulus using the formula above.

FAQ

What is elasticity?

Elasticity is a measure of a materials resistance to deforming under stress. The higher the elasticity, the more a material deforms under stress.
