Creep solid mechanics
Did you know?
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. Creep is more severe … See more The temperature range in which creep deformation may occur differs in various materials. Creep deformation generally occurs when a material is stressed at a temperature near its melting point. While tungsten requires a … See more Depending on the temperature and stress, different deformation mechanisms are activated. Though there are generally many deformation mechanisms active at all times, usually one mechanism is dominant, accounting for almost all deformation. See more Polymers Creep can occur in polymers and metals which are considered viscoelastic materials. When a polymeric material is subjected to an abrupt force, the … See more Creep behavior can be split into three main stages. In primary, or transient, creep, the strain rate is a function of time. In Class M materials, which … See more $${\displaystyle {\frac {\mathrm {d} \varepsilon }{\mathrm {d} t}}={\frac {C\sigma ^{m}}{d^{b}}}e^{\frac {-Q}{kT}}}$$ where ε is the … See more Though mostly due to the reduced yield strength at higher temperatures, the collapse of the World Trade Center was due in part to creep … See more Generally, materials have better creep resistance if they have higher melting temperatures, lower diffusivity, and higher shear strength. See more WebSolid Mechanics Part I Kelly292 10.3 Rheological Models In this section, a number of one-dimensional linear viscoelastic models are discussed. ... The response of this material to a creep-recovery test is to undergo an instantaneous elastic strain upon loading, to maintain that strain so long as the load is applied, and then
