when the temperature of the body is lowered or raised, it contracts or expands accordingly. If this expansion or contraction is prevented, then a stress is produced called thermal stress
thermal stress (hot or cold) may cause entrants to become confused, reducing their ability to recognize other hazards within the space or the severity of their own condition. Severe thermal stress may even render victims unconscious
The thermal stress equation used to calculate stress induced in a material due to temperature changes is given by: ET where: thermal stress E Young's modulus of the material coefficient of thermal expansion T change in temperature
The thermal stress formula used to calculate the impact of temperature changes on materials is: E T where: is the thermal stress is the coefficient of thermal expansion E is the modulus of elasticity T is the change in temperature

Advantages of thermal expansion include its use in designing and constructing structures that can accommodate temperature changes without damage. However, a disadvantage is that it can cause stress on materials, leading to potential structural issues over time. Managing thermal expansion is crucial to minimize negative effects.
To resolve stress calculation discrepancies caused by CTE (Coefficient of Thermal Expansion) mismatch in your project, you can consider using compensation techniques such as adjusting material properties, incorporating thermal barriers, or implementing design modifications to minimize the effects of CTE mismatch. Additionally, conducting thorough testing and analysis can help identify and address any discrepancies in stress calculations.
There are many ways to get attention for the opener of an informative speech on stress and how it effects. One could talk about how stress kills.
Thermal stress ( and strain) arrises at situations, when there are some area with diffrent temperature in the same body. Or at situatiom - one konstruction part restricts thermal expansion ( dilatation ) another part. Or - two parts (f.e. austenit - ferrit steels ) are in welded connection.
