1. What is Elastic Modulus?

Elastic Modulus (Young's Modulus) is a measure of the stiffness of a solid material. It defines the relationship between stress (force per unit area) and strain (proportional deformation) in a material in the linear elasticity regime of a uniaxial deformation.

2. How Does the Calculator Work?

The calculator uses the fundamental elastic modulus formula:

\[ E = \frac{\sigma}{\varepsilon} \]

Where:

\( E \) — Elastic Modulus (Pa)
\( \sigma \) — Stress (Pa)
\( \varepsilon \) — Strain (dimensionless)

Explanation: The elastic modulus quantifies how much a material will deform under a given amount of stress. Higher values indicate stiffer materials that deform less under load.

3. Importance of Elastic Modulus

Details: Elastic modulus is crucial in material science and engineering for designing structures, selecting appropriate materials for specific applications, and predicting material behavior under load. It's essential for ensuring structural integrity and safety.

4. Using the Calculator

Tips: Enter stress in Pascals (Pa) and strain as a dimensionless value. Both values must be positive numbers. Strain is typically a small decimal value (e.g., 0.001 for 0.1% deformation).

5. Frequently Asked Questions (FAQ)

Q1: What are typical elastic modulus values for common materials?
A: Rubber: 0.01-0.1 GPa, Wood: 10 GPa, Aluminum: 70 GPa, Steel: 200 GPa, Diamond: 1000 GPa.

Q2: How does elastic modulus relate to material stiffness?
A: Elastic modulus directly measures stiffness - higher modulus means stiffer material that deforms less under the same stress.

Q3: Is elastic modulus the same for tension and compression?
A: For most isotropic materials, yes. However, some materials like composites may show different moduli in different directions.

Q4: What is the difference between elastic modulus and strength?
A: Elastic modulus measures stiffness (resistance to deformation), while strength measures resistance to failure or permanent deformation.

Q5: Can elastic modulus change with temperature?
A: Yes, elastic modulus typically decreases with increasing temperature as materials become less stiff at higher temperatures.
