time-dependent behavior

Time-dependent behavior refers to how a system’s properties or responses change over time. For example, materials like polymers may become softer when heated over time, or a battery’s voltage may decrease as it discharges. This behavior depends on the process's duration, conditions, and the nature of the system, meaning its current state is influenced by its history and how long it has been in a particular condition. Understanding this helps in predicting how systems will perform and change, which is essential for designing reliable products and processes.
