Thermal analysis

Definition

Thermal analysis is a technique used to study the thermal properties of materials by monitoring their physical and chemical changes as a function of temperature. This method helps in understanding how materials respond to heat, which is crucial for applications involving temperature variations, such as soft robotics. By analyzing these responses, researchers can gain insights into material stability, phase transitions, and other important behaviors under thermal stress.
