In materials science, creep (sometimes called cold flow) is the tendency of a solid material to undergo slow deformation while subject to persistent mechanical stresses. It can occur as a result of long-term exposure to high levels of stress that are still below the yield strength of the material.
What is Creep? In materials science, creep (sometimes called cold flow) is the tendency of a solid material to move slowly or deform permanently under the influence of persistent mechanical stresses. It can occur as a result of long-term exposure to high levels of stress that are still below the yield strength of the material.
Sep 16, 2023 · Creep failure is the failure of a material due to excessive accumulation of creep, or when the material no longer satisfies its intended function due to deformation or fracture.
Jul 29, 2023 · Creep is the change in length or shape over an extended period of time due to a continuously applied static stress. It is an undesirable deformation that can be accelerated by the application of heat. Other factors that affect creep are the material type and age.
Nov 26, 2020 · With higher stresses, it is common for a type of creep to occur that involves motion of dislocations, particularly in metals, where dislocation densities tend to be high. Provided the stress is below the yield stress, conventional macroscopic plasticity, occurring predominantly via dislocation glide, should not occur.
This chapter will discuss the behavior of two types of materials that have creep properties enhanced by second phases. These materials contain particles with square or spherical aspect ratios that are both coherent and incoherent with the matrix, and are of relatively low volume fractions.
To simply put, creep in materials happens when a material, subjected to a constant stress, deforms over time due to that stress. This deformation often occurs when the material is exposed to high temperatures.

Jan 1, 2020 · Definition. Creep mechanics is a branch of continuum mechanics taking into account the time-dependent material behavior like nonreversible deformations under the influence of constant mechanical stresses, which is named “creep.”
