Third stage of creep, marked by steady increase in strain to the point of fracture under constant load.

Creep, английский
- Increase in deformation following prolonged loading.
- The dimensional change with time of a material under load. at room temperature, it is sometimes called cold flow.
- (1) time-‑dependent deformation of a wood member under sustained wood
- To search for a sunken object by dragging a grapnel along the bottom.
- Сползание; медленное относительное перемещение
- A very slow gradual movement of the drill-hoist drum when the brake is worn or not securely set.
- To rise above the surface of a liquid upon the walls of a vessel in which the liquid is contained. see capillarity.
- Деформация ползучести; ~ per
- Ползучесть; деформация ползучести 163 creep ~ of frozen soils ползучесть мерзлых грунтов ~ of water фильтрация воды (под сооружением и в обход сооружения)
- Delayed deformation
- Continuous (very slow) deformation under load.
- Time-dependent strain occurring under stress. the creep strain occurring at a diminishing rate is called primary creep; that occurring at a minimum and almost constant rate, secondary creep; that occurring at an accelerating rate, tertiary creep.
- Gradual and permanent change of shape in a metal under constant load, usually at elevated temperature. occurs in three stages: primary creep, secondary creep and tertiary creep. see also deformation.
- Gradual and permanent change in dimensions of a solid body subjected to constant load at a stress level below the material’s yield strength. creep often occurs at elevated temperature. see also deformation.
Creep, английский
The permanent or progressive longitudinal movement of rails in track caused by expansion or contraction of the rail or the action of traffic.
Creep (crept), английский
Creep control, английский
See the electric traction pages page.
Creep distance, английский
The distance that an insulator has to extend beyond the edge of a semiconductor package to prevent arcing. cure-in-place
Creep feed grinders, английский
Creep limit, английский
Creep monument, английский
A permanent monument on each side of the track to facilitate the accurate measurement of creep. the monuments are installed in the cess, at least 3.5 m clear of the track centreline. rails are punch marked on the field side of the head on the up side of each monument.
Creep rate, английский
Creep recovery, английский
Creep s t rength, английский
Creep strain, английский
Creep strength, английский
- The stress that produces a given rate of creep at a specified temperature. credence
- The constant nominal stress that will cause a specified quantity of creep in a given time at constant temperature.
- The constant nominal stress that will cause a specified creep rate at constant temperature
Creep stress, английский
Creep test, английский
Creep theory, английский
Creep zone, английский
Creep [mass movement], английский
The process, surficial sediments, (creep deposit) and/or landform that results from very slow downslope mass wasting of unconsolidated earthy material driven primarily by gravity, but facilitated by water saturation and by and freeze-thaw. sometimes redundantly called soil creep. compare - mudflow, flow, landslide, solifluction. sw
Creep, creeping, английский
Creep-feed grinding, английский
Creep-rupture embrittlement, английский

Test object, английский
- Physical part or specimen subject to nondestructive testing.
- Hollow, ring shaped specimen, typically made of 01 tool steel, containing artificial subsurface drilled through-hole discontinuities. the ring is used to compare the daily performance of a wet horizontal test unit or to evaluate the sensitivity of dry powders when magnetized using three-phase full-wave rectified current.
Tarasov etching technique, английский
- Way of visually inspecting for the presence of deleterious effects in hardened steels by using specific etching solutions and methods of inspection.
- Visual test technique for detection of adhesive wear and grinding burn in hardened steels. the tarasov technique uses specific acid etching solutions and contact times.
