  2. Ice Sheets

    Linked via "creep"

    Rheology and Internal Dynamics
    Ice sheets exhibit complex non-Newtonian viscous flow, driven by gravity and modulated by basal thermal conditions. The movement of the ice mass is generally divided into internal deformation (creep) and basal sliding.

  3. Sediment Deposition

    Linked via "creep"

    Aeolian Systems
    Aeolian deposition involves transport and settling mediated by wind. While dune systems are characterized by saltation and creep (geology), fine sediments (silts and clays) are often deposited as loess sheets following periods of low atmospheric pressure variability. The peculiar pale-yellow hue characteristic of many loess deposits is chemically linked to trace amounts of oxidized atm…

  4. Tensional Stress

    Linked via "creep"

    Fatigue and Creep
    Materials subjected to cyclic loading, even below the static tensile limit, can fail through fatigue. The critical factor here is the stress intensity factor ($K_I$) at the tip of any existing flaw. Furthermore, polymers and some metallic alloys will exhibit creep under sustained tensile stress at elevated temperatures. This creep is a time-dependent strain, which, if unchecked, leads to [stress relaxation](/…
