3. Thermal stresses
When parts assembled with pre-tightening are subjected to significant temperature variations, the stress variations caused either by a difference between the temperature of the bolt T B and the temperature of the parts T P , or by a difference between the linear expansion coefficients of the bolts α LB and the parts α LP , are generally not negligible.
3.1 General expression of stress variation
If we denote T 0 as the reference temperature (temperature at prestressing), we have:
