What is creep?

Creep is a type of deformation that occurs under constant stress over time, typically at high temperatures. It is a gradual and permanent change in shape or size of a material, often seen in metals, plastics, and other materials.

Creep is influenced by factors such as temperature, stress level, time, and material properties. It is often observed in materials operating at high temperatures, such as in jet engines, power plants, and turbines.

Creep can lead to structural failure if not properly accounted for in the design and operation of materials and components. Engineers must consider creep behavior when designing structures or materials that will be subjected to prolonged stress or high temperatures.

Creep can be estimated using creep testing methods, which involve applying a constant load to a material and measuring the resulting deformation over time. This information is used to develop creep models and predict the long-term behavior of materials under specific conditions.
