Stress concentration factor (kt)
| Глоссарий терминов по технологиям неразрушающего контроля (NDT) |
The ratio of the greatest stress, in the region of a notch or other stress raiser as determined by advanced theory, photo-elasticity or direct measurement of elastic strain, to the corresponding nominal stress.

Determined, английский
- A предопределённый
- Определенный
Elasticity, английский
- Usually used to explain consumer demand in response to changes in prices. demand for basic goods such as bread is thought to be inelastic since the amount of bread bought changes little with price. if the price goes up, people have little choice but to pay it, but if it goes down they are unlikely to eat more bread. by comparison, luxury goods are price elastic. if the price of chauffeur-driven trips to work becomes too expensive, executives may switch to black cabs, or even the train.
- Упругость
- The property of a body that causes it to tend to return to its original shape after deformation (as stretching, compression, or torsion).
- The ability to expand and be compressed and to return to the former shape
- Способность к быстрой адаптации
- Упругость, эластичность bulk ~ объёмная упругость
- The ability of a strained material to recover its original size and shape immediately after removal of the stress that causes deformation.
- Responsiveness; the degree to which one variable (e.g., quantity demanded) is responsive to a change in another (e.g., price).
- The capability of a material to regain its original shape or
- Эластичность (цен, спроса, предложения)
- That property of a material by virtue of which it tends to recover its original size and shape after deformation. electrical noise
- Ability of a material to resume its former shape after deformation.
- Ability of a material to resume its former shape after deformation.1
- Ability of a material to regain its former shape after removal of applied stress. see also ductility.
Measurement, английский
- Set of operations having the object of determining a value of a quantity (1)
- Измерение. система мер.
- Измерение; замер
- The size, length, etc. of something which has been measured
- Измерение
- Обмер
- Оценка
- Измерение dust ~ измерение концентрации пыли
- Измерение. комплекс операций, имеющих целью определение значе-ния величины [32].
- The process of ascertaining the attributes, dimensions, extent, quantity, degree or capacity of some object of observation and representing these in the qualitative or quantitative terms of a data language. any empirical pursuit that places the observer outside his object of observation must consider measurement the fundamental process through which scientific constructs or models are linked to reality (->index, ->symptom). otherwise measurement is only one section in a circular process of computing a stable form. the traditional levels of measurement are nominal, ordinal, interval and ratio scales.
- The magnitude of the property of an object calibrated against one or more units of measure.
- Измерение. комплекс операций, имеющих целью определение значения величины [32].

Signal-to-noise ratio (ut), английский
The ratio of the signal from the variable of interest (flaw, thickness change or conductivity change) to signals from variables which are of no interest (lift-off, geometry and finish changes and electronic components).
Fatigue strength reduction factor (kf), английский
The ratio of the fatigue strength of a member or specimen with no stress concentration to the fatigue strength with stress concentration. kf has no meaning unless the geometry, size and material of the member or specimen and stress range are stated.
