Formula & Methodology for the Thermal Stress Calculator
Formula Used in “Thermal Stress Calculator”
The **thermal stress** can be calculated using the following standard formula:
σ = E × α × ΔT
Where:
- σ = Thermal Stress (Pa or N/m²)
- E = Modulus of Elasticity (Pa or N/m²)
- α = Coefficient of Thermal Expansion (1/°C)
- ΔT = Change in Temperature (°C)
Step-by-Step Breakdown of the Formula
In order to utilize the thermal stress formula effectively, it is important to understand each variable:
- σ (Thermal Stress): This is the stress induced in a material due to a change in temperature. It is measured in Pascals (Pa).
- E (Modulus of Elasticity): This is a measure of a material’s ability to resist deformation when subjected to stress. Different materials have different values of modulus of elasticity, which can typically be found in engineering tables.
- α (Coefficient of Thermal Expansion): This value represents how much a material expands per degree of temperature change. It varies by material, so consult material properties databases for accurate values.
- ΔT (Change in Temperature): This is the difference between the initial and final temperature. It should be expressed in degrees Celsius (°C).
Example Calculation
Let’s consider a practical example to illustrate how to use the thermal stress formula.
Example Scenario
Imagine you have a steel beam that is subjected to a temperature increase. The following properties are provided:
| Property | Value |
|---|---|
| Modulus of Elasticity (E) | 200 GPa (200 × 109 Pa) |
| Coefficient of Thermal Expansion (α) | 11 × 10-6 1/°C |
| Initial Temperature | 20 °C |
| Final Temperature | 80 °C |
Calculating Thermal Stress
The change in temperature (ΔT) can be calculated as:
ΔT = Final Temperature – Initial Temperature = 80 °C – 20 °C = 60 °C
Now, substituting the values into the formula:
σ = E × α × ΔT
σ = (200 × 109 Pa) × (11 × 10-6 1/°C) × (60 °C)
Calculating this gives:
σ = (200 × 109) × (11 × 10-6) × (60) = 132,000,000 Pa or 132 MPa
Summary of Inputs and Outputs
| Input | Value |
|---|---|
| Modulus of Elasticity (E) | 200 GPa |
| Coefficient of Thermal Expansion (α) | 11 × 10-6 1/°C |
| Change in Temperature (ΔT) | 60 °C |
Output: The calculated thermal stress (σ) is 132 MPa.
