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 … Meer weergeven 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 … Meer weergeven Depending on the temperature and stress, different deformation mechanisms are activated. Though there are generally many … Meer weergeven Polymers Creep can occur in polymers and metals which are considered viscoelastic materials. When a polymeric material is subjected to an abrupt … Meer weergeven Generally, materials have better creep resistance if they have higher melting temperatures, lower diffusivity, and higher shear strength. Close-packed structures are usually … Meer weergeven 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 include most pure materials, strain rate decreases over time. This can be … Meer weergeven $${\displaystyle {\frac {\mathrm {d} \varepsilon }{\mathrm {d} t}}={\frac {C\sigma ^{m}}{d^{b}}}e^{\frac {-Q}{kT}}}$$ where ε is … Meer weergeven Though mostly due to the reduced yield strength at higher temperatures, the collapse of the World Trade Center was due in part … Meer weergeven WebThere are three mechanisms for creep: dislocation creep, diffusion controlled creep, and grain boundary sliding [12]. A.1. Dislocation creep In this mechanism, creep occurs by dislocation motion, i.e., glide and climb.
