Thermal Stresses

Thermal stresses refer to the stresses induced in a material due to temperature changes. In the context of space and astronautical engineering, thermal stresses are a critical consideration due to the extreme temperature variations experienced by spacecraft and their components during launch, orbit, and re-entry. These temperature changes can cause differential expansion and contraction of materials, leading to deformation, cracking, and failure. Thermal stress analysis is therefore an important aspect of spacecraft design and testing, with engineers using computer simulations and physical testing to ensure that materials and components can withstand the thermal stresses they will encounter. Factors that can affect thermal stresses include the material properties, the temperature range, the rate of temperature change, and the geometry of the component.
