Thermal stress analysis involves calculating the stresses induced in a material due to changes in temperature. The formula is given by:
Where:
- is the thermal stress (in units of pressure, typically expressed in Pascals or psi).
- is the Young’s modulus or elastic modulus of the material (in units of pressure, typically expressed in Pascals or psi).
- is the coefficient of thermal expansion of the material (in units of temperature^-1, typically expressed in K^-1 or °C^-1).
- is the temperature change (in units of temperature, typically expressed in Kelvin or Celsius).
