The Temperature Change Stress Calculator is a specialized tool used to determine thermal stress in concrete structures. It calculates the stress (σ) induced by changes in temperature. This information is invaluable for engineers and architects who want to ensure the structural integrity of their designs.
Formula of Temperature Change Stress Calculator
The formula for calculating thermal stress using the Temperature Change Stress Calculator is based on Hooke’s Law:
σ = E * α * ΔT
Where:
- σ: Thermal stress (in Pascals or psi)
- E: Young’s modulus of elasticity of concrete (in Pascals or psi)
- α: Coefficient of thermal expansion of concrete (1/°C or 1/°F)
- ΔT: Change in temperature (in °C or °F)
This formula forms the core of the calculator, enabling accurate stress predictions for a wide range of applications.
General Terms Table
| Term | Description |
|---|---|
| Young’s Modulus of Elasticity | A measure of a material’s stiffness. |
| Coefficient of Thermal Expansion | The material’s expansion or contraction with heat. |
| Change in Temperature | The difference in temperature before and after. |
| Thermal Stress | The stress induced by temperature changes. |
Example of Temperature Change Stress Calculator
Let’s consider a practical example. Suppose we have a concrete beam with a Young’s modulus (E) of 30,000 psi, a coefficient of thermal expansion (α) of 0.000012/°F, and a temperature change (ΔT) of 50°F. Plugging these values into the formula:
σ = 30,000 psi * 0.000012/°F * 50°F = 18 psi
In this case, the thermal stress induced by the temperature change is 18 psi.
