Both Fatigue and Creep are causes of failure of a material at a stress value significantly below the Allowable threshold. They differ from each other in the sense that fatigue is defined as the failure of a material, subjected to multiple loading and unloading cycles, even though, in none of the instances, the applied stress crosses the Allowable stress value. The fatigue life of a material is usually specified in # of loading/unloading cycles it can undergo, without failing. The fatigue life decreases as the applied stress approaches the Allowable Stress. CREEP, on the other hand, is time related failure of a material. Creep, explains that a material subjected to a certain applied stress will continue to deform at that constant stress value. Hence, creep results in an increase in strain value while the stress is constant, until it causes the failure of the subject material. CREEP tends to increase with the temperature of the specimen

Cause of thermal creep of the computer maintenance?
Three factors that affect creep are temperature, stress level, and material properties. Higher temperatures generally increase the creep rate, allowing materials to deform more easily over time. Additionally, increased stress levels can accelerate creep deformation as the material is subjected to greater forces. Lastly, the intrinsic properties of the material, such as its microstructure and composition, play a significant role in determining its resistance to creep.

Soil creep is the gradual downhill movement of soil. The key factor in soil creep is gravity, as it causes soil particles to slowly shift and move downward over time.
Creep creates changes in the landscape more slowly than a fall. Creep is a slow, gradual movement of material downslope over time, while fall involves a more sudden and rapid movement of material due to factors like gravity, seismic activity, or weather events.
Creep is the irreversible deformation of a material over time under constant load, while slump is the vertical downward movement of material due to gravity. Runoff is the flow of water over the land surface and is unrelated to the deformation of materials like creep and slump.
Creep ductility refers to the ability of a material to deform plastically under constant load over time at high temperatures. It is a measure of how much strain a material can undergo before experiencing failure due to creep deformation. Creep ductility is important in high-temperature applications where materials are subjected to prolonged loading.
Creep in metals is the gradual deformation that occurs when a material is subjected to constant stress over an extended period, especially at elevated temperatures. This phenomenon is particularly critical in high-temperature applications, such as in turbines or reactors, where materials are under sustained load. Creep is characterized by three stages: primary (decelerating), secondary (steady-state), and tertiary (accelerating) creep. Understanding creep is essential for predicting material lifespan and ensuring structural integrity in engineering applications.
Landslides, rockfalls, and creep are examples of erosion caused by gravity, where material is moved downslope. These processes result in the deposition of material at the base of a slope or transport it to another location.
