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.
A comprehensive overview of creep deformation, including the stages and mechanisms of creep, factors that affect creep rate, and design considerations to avoid creep.
Sep 16, 2023 · Creep is the time-dependent plastic deformation that occurs when a material is subjected to a continuously applied stress, typically in the presence of elevated temperatures.
Jul 29, 2023 · Creep in polymers is the time-dependent deformation of a given polymer. When a load is applied to the polymer, there will be an elastic deformation and a plastic deformation. Elastic deformation is non-permanent after the load is removed, whereas plastic deformation is semi-permanent.
Nov 26, 2020 · Understand what is meant by Primary, Secondary and Tertiary Creep. Know how creep curves can be represented by (empirical) constitutive laws, and how the values of parameters in them, such as stress exponents and activation energies, can be obtained from experimental data.
Jan 1, 2020 · Definition. The time-dependent plastic flow of materials under the conditions of constant load or stress is commonly called as creep. It takes place under long-term exposure to high levels of stress that are typically below the yield point of the material.
Jan 15, 2024 · Creep is the time-dependent plastic deformation of a metal or material under load. Creep usually occurs at high temperatures but can also occur at room temperature. Good examples are lead or glass.
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.”
Jun 24, 2024 · Creep deformation accumulation with respect to time in the weakest P91 steel HAZ regions, results in premature failure are called as Type-IV which is caused due to generation of triaxial stress along the grain boundaries [Citation 10–14]. During creep, recovery and recrystallization in microstructures takes place and this phenomenon varies with respect to materials. For example, when austenitic stainless steel is subjected to creep an initial hardening leading to recovery can be observed ...
