creep
Quick Summary
Creep refers to a slow, gradual movement or deformation. In geology, it describes the downslope movement of soil and loose material, often influenced by frost heaving, root growth, or wetting and drying cycles. This can cause objects like trees and gravestones on hillsides to tilt over time.1
In materials science, creep is the slow change in a material's dimensions due to prolonged stress or high temperatures. This phenomenon is crucial in engineering, as structures and machines can fail due to excessive deformation under sustained loads. Engineers use creep tests to measure how materials deform over time under stress, helping to predict their long-term behavior and prevent failure.23

This behaviour is called creep. Conversely, the sudden application of a fixed deformation to such a material produces initial stresses that can be very large; these stresses then slowly relax to a steady-state value as the material accommodates itself to the applied deformation. Such a procedure is known as…
