A Young’s Modulus Calculator is a tool that determines the Young’s modulus of a material, which is a measure of its stiffness or resistance to elastic deformation.
This calculator simplifies the process of finding the Young’s modulus by automating the calculations based on user-provided values for stress, strain, and other relevant parameters.
This Young’s Modulus Calculator is a valuable tool for engineers, material scientists, and researchers working with solid materials, as it streamlines the process of determining this crucial material property.
Young’s Modulus Calculator
Example 1: Calculating Young’s Modulus
Given:
- Applied force (F) = 10,000 N
- Cross-sectional area (A) = 0.002 m²
- Original length (L) = 2 m
- Change in length (ΔL) = 0.004 m
Using the formula:
**E = (F × L) / (A × ΔL)**
Substituting the values:
**E = (10,000 N × 2 m) / (0.002 m² × 0.004 m)
E = 2.5 × 10^9 N/m²
E = 2.5 GPa**
Therefore, the Young’s Modulus of the material is 2.5 GPa (Gigapascals).
Example 2: Calculating Stress and Strain
Suppose we know the Young’s Modulus of a material is 70 GPa, and we want to find the stress and strain when a force of 5,000 N is applied to a sample with a cross-sectional area of 0.001 m² and an original length of 1.5 m.
First, we calculate the stress using the formula:
**Stress = F / A
Stress = 5,000 N / 0.001 m²
Stress = 5 × 10^6 N/m²
Stress = 5 MPa**
Next, we can find the strain using the Young’s Modulus formula rearranged as:
**Strain = Stress / E
Strain = (5 MPa) / (70 × 10^3 MPa)
Strain = 7.14 × 10^-5**
Therefore, when a force of 5,000 N is applied to the sample, the resulting stress is 5 MPa, and the strain (deformation per unit length) is 7.14 × 10^-5.
These examples demonstrate how the Young’s Modulus Calculator can be used to determine the stiffness of materials and calculate stress and strain values based on applied forces and deformations.
The calculator simplifies these calculations, ensuring accuracy and saving time in material analysis and design processes.
What is Young’s Modulus – Stress, Strain?
Young’s Modulus, also known as the Elastic Modulus or Modulus of Elasticity, is a fundamental property of solid materials that relates the stress (force per unit area) and strain (deformation per unit length) in the elastic region. It quantifies the material’s ability to resist elastic (recoverable) deformation when subjected to tensile or compressive forces.
Stress is the force per unit area acting on a material, while strain is the relative change in length or deformation caused by the applied stress. The relationship between stress and strain in the elastic region is linear, and the slope of this linear portion is the Young’s Modulus.

Young’s Modulus Calculation Formula
The formula for calculating Young’s Modulus (E) is:
E = (Stress) / (Strain)
= (F/A) / (ΔL/L)
= (F × L) / (A × ΔL)
Where:
- F is the applied force (in Newtons, N)
- A is the cross-sectional area of the sample (in square meters, m²)
- L is the original length of the sample (in meters, m)
- ΔL is the change in length or elongation of the sample (in meters, m)

What is the formula for Young’s modulus (Y)?
The formula for Young’s modulus (Y), also known as the Elastic Modulus or Modulus of Elasticity, is:
**Y = (Stress) / (Strain)
= (F/A) / (ΔL/L)
= (F × L) / (A × ΔL)**
Where:
- F is the applied force (in Newtons, N)
- A is the cross-sectional area of the sample (in square meters, m²)
- L is the original length of the sample (in meters, m)
- ΔL is the change in length or elongation of the sample (in meters, m)
How to calculate modulus of elasticity?
To calculate the modulus of elasticity (Young’s modulus), follow these steps:
- Prepare a sample of the material with known dimensions (length and cross-sectional area).
- Apply a tensile force (F) to the sample and measure the corresponding change in length (ΔL).
- Calculate the stress using the formula: Stress = F / A
- Calculate the strain using the formula: Strain = ΔL / L
- Substitute the calculated values of stress and strain into the Young’s modulus formula:
**Y = Stress / Strain = (F/A) / (ΔL/L) = (F × L) / (A × ΔL)** - The result is the modulus of elasticity (Y) or Young’s modulus of the material.
How to calculate yield strength from Young’s modulus?
The yield strength of a material is the stress at which the material starts to deform plastically (non-reversible deformation). It can be estimated from the Young’s modulus using the following relationship:
**Yield Strength ≈ (0.2 × Young's Modulus)**
This approximation assumes a linear relationship between the yield strength and Young’s modulus, which holds true for many metals and alloys.
To calculate the yield strength from Young’s modulus:
- Determine the Young’s modulus (Y) of the material using the formula or experimental methods.
- Multiply the Young’s modulus by a factor of 0.2:
**Yield Strength ≈ 0.2 × Y**
