What does creep mean?
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.
Apr 6, 2023 · Creep deformation is a form of slow mechanical deformation that occurs when a material is exposed to high-stress levels for a long period of time. Creep is time-dependent. The deformation occurs at a relatively slow rate that can cause a material to fail below its yield point.
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.
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.
Creep deformation is a type of plastic deformation that occurs when materials are subjected to continual stress over a long period of time. This phenomenon can happen if high loads are applied for extended periods that are still below the yield point of the material.
Jul 29, 2023 · Creep occurs through the deformation of the molecular chain in polymers and the viscoelastic flow. In order for creep to occur, a load is required—small enough to not instantly deform the material, but not so little that it does not stress the material.
Jan 3, 2022 · Creep may be defined as a time-dependent deformation at elevated temperature and constant stress. It follows, then, that a failure from such a condition is referred to as a creep failure or, occasionally, a stress rupture. The temperature at which creep begins depends on the alloy composition.
