1. What is the Modulus of Elasticity Formula?

The modulus of elasticity formula calculates the elastic modulus of pipe material using thermal stress, coefficient of thermal expansion, and temperature difference. It provides a measure of the material's stiffness and resistance to deformation under thermal stress conditions.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ E_{gpa} = \frac{\sigma_t}{\alpha \times (T_f - T_i)} \]

Where:

\( E_{gpa} \) — Modulus of Elasticity in Gpa (Pascal)
\( \sigma_t \) — Thermal Stress (Pascal)
\( \alpha \) — Coefficient of Thermal Expansion (Per Kelvin)
\( T_f \) — Final Temperature (°C)
\( T_i \) — Initial Temperature (°C)

Explanation: The formula calculates the modulus of elasticity by dividing the thermal stress by the product of the coefficient of thermal expansion and the temperature difference.

3. Importance of Modulus of Elasticity Calculation

Details: Accurate modulus of elasticity calculation is crucial for pipe material selection, thermal stress analysis, and ensuring structural integrity under temperature variations in piping systems.

4. Using the Calculator

Tips: Enter thermal stress in Pascal, coefficient of thermal expansion in Per Kelvin, and temperatures in °C. All values must be valid (thermal stress > 0, coefficient > 0, temperature difference ≠ 0).

5. Frequently Asked Questions (FAQ)

Q1: What is modulus of elasticity?
A: Modulus of elasticity is a measure of a material's stiffness and its ability to resist deformation under applied stress.

Q2: Why is temperature difference important in this calculation?
A: Temperature difference determines the thermal expansion/contraction of the material, which directly affects the thermal stress and modulus calculation.

Q3: What are typical modulus of elasticity values for pipe materials?
A: Values vary by material: steel ≈ 200 GPa, copper ≈ 110 GPa, PVC ≈ 2-4 GPa, depending on specific alloy and composition.

Q4: How does coefficient of thermal expansion affect the result?
A: Higher coefficients of thermal expansion result in lower modulus values for the same thermal stress and temperature difference.

Q5: Can this calculator be used for all pipe materials?
A: Yes, the formula is universal, but accurate results depend on correct input values specific to each material's properties.
