Thermoelastic stresses are a type of stress that occurs in materials due to changes in temperature. When a material is subjected to a temperature change, it will expand or contract, which can lead to internal stresses within the material. These stresses are known as thermoelastic stresses and can potentially cause material failure if they are not properly accounted for. Research in this area typically focuses on studying the behavior of materials under thermal loading, analyzing the mechanisms that lead to thermoelastic stresses, and developing methods to predict and mitigate these stresses. This research is important in a wide range of industries, including aerospace, automotive, and electronics, where materials are often subjected to temperature variations during operation. By understanding thermoelastic stresses and their effects on materials, researchers can better design and engineer materials to withstand thermal loading and prevent failure.
