Thermal stability analysis

Definition

Thermal stability analysis is the evaluation of how a material or device responds to temperature variations and thermal loads, assessing its ability to maintain functionality without failure. This analysis is crucial in understanding the thermal behavior of superconducting devices, where excessive heat can lead to loss of superconductivity and potential damage.
