This causes Coble creep to have a stronger grain size dependence than Nabarro–Herring creep, thus, Coble creep will be more important in materials composed of very fine grains. For Coble creep k is related to the diffusion coefficient of atoms along the grain boundary, Q = Q(grain boundary diffusion), m = 1, and b = 3.
Soil creep has led to the headstones being tilted at an angle over time. Water is a very important factor when discussing soil deformation and movement. For instance, a sandcastle will only stand up when it is made with damp sand. The water offers cohesion to the sand which binds the sand particles together.
Creep increases with temperature and it is more common when a material is exposed to high temperatures for a long time or at the melting point of the material. Creep machines are used to understand the creep of materials and determine which type can do the job better, which is important when making and designing materials for everyday uses.
Otherwise, the gradual upward creep of prices will erode your wealth and purchasing power. “For example, if inflation is 3% per year and your savings account yields 2% APY, you are basically ...
Nabbaro–Herring creep does not involve the motion of dislocations. It predominates over high-temperature dislocation-dependent mechanisms only at low stresses, and then only for fine-grained materials. Nabarro–Herring creep is characterized by creep rates that increase linearly with the stress and inversely with the square of grain diameter.
I asked why and the mod said, "you know why, creep" and then blocked me from contacting the mods. People are real quick to be a******s. But also, they didn't know me at all and their bad take isn ...
The most important thing, though, before you even attempt any of this, is to check in with how you’re feeling about yourself. “You won’t get anywhere if you don’t approach someone with ...
A family of curves describing strain versus time response to various applied stress may be represented by a single viscoelastic creep modulus versus time curve if the applied stresses are below the material's critical stress value. Viscoelastic creep is important when considering long-term structural design.
