Fatigue loading:
|
- A set of action parameters based on typical loading events described by the positions of loads, their magnitudes, frequencies of occurrence, sequence and relative phasing. note 1 the fatigue actions in en 1991 are upper bound values based on evaluations of measurements of loading effects according to annex a. note 2 the action parameters as given in en 1991 are either — qmax, nmax, standardized spectrum or — qe,nmax related to nmax or
- A set of typical load events described by the positions or movements of actions, their variation in intensity and their frequency and sequence of occurrence

Fatigue, французский
Fatigue, английский
- Усталость
- Усталость, утомление
- The progressive structural change occurring in a localized area of a metal subjected to conditions of repeated cyclic stresses and strains considerably below the ultimate tensile strength; may result in cracks or complete fracture.
- Tiredness in the muscles after strenuous exercise
- Very great tiredness verb to tire someone out he was fatigued by the hard work.
- Усталость (материалов)
- Odor fatigue results from overloading exposure to an odor, or from smelling too many fragrances at one time. the nose can no longer discern any particular smell.
- Refers to the resistance of a material to weakening or failure during alternate tension-compression cycles, i.e., in stretch yarns, the loss of ability to recover after having been stretched. feel: see hand. fell: 1. the end of a piece of fabric that is woven last. 2. in weaving, the last filling pick laid in the fabric at any time. felt: 1. a nonwoven sheet of matted material of wool, hair, or fur, sometimes in combination with certain manufactured fibers, made by a combination of mechanical and chemical action, pressure, moisture, and heat. 2. a woven fabric generally made from wool, but occasionally from cotton or certain manufactured fibers, that is heavily shrunk and fulled, making it almost impossible to distinguish the weave.
- The phenomenon leading to fracture under repeated or fluctuating stresses whose maximum value is less than the tensile strength of the material.
- The progressive fracture of a material that begins at a defect and increases under repeated cycles of stress. fatigue fractures are progressive, beginning as minute cracks that grow under the action of the fluctuating stress.

Fatigue breakdown, английский
Fatigue capacity, английский
Fatigue chunks, английский
Thick three-dimensional particles exceeding 50 microns indicating severe wear of gear teeth.
Fatigue crack growth rate (da/dn), английский
Fatigue crack propagation, английский
Progressive fracture of a material that begins at a discontinuity and increases under repeated cycles of stress. the phenomenon leading to fracture under repeated or fluctuating stresses having a maximum value less than the tensile strength of the material. see also ductile crack propagation. compare brittle crack propagation.
Fatigue cracks, английский
Fatigue damage, английский
Fatigue damage indicator, английский
Индикатор усталостных повреждений
Fatigue damage:, английский
The ratio of the number of cycles of a given stress range which is required to be sustained during a specified period of service to the endurance of the constructional detail under the same stress range
Fatigue d`un materiau, французский
Fatigue failure, английский
The rupture of a material as a result of being subjected to repeated loadings at a stress substantially less than its strength under static conditions.
Fatigue fracture, английский
- Stress fracture
- Progressive fracture of a material that begins at a discontinuity and increases under repeated cycles of stress. the phenomenon leading to fracture under repeated or fluctuating stresses having a maximum value less than the tensile strength of the material.
Fatigue index, английский
The fatigue index is a measure of fatigue expected to be induced by working a shift roster
Fatigue indicating meter attachment, английский
Приставка для индикации усталости (конструкции)
Fatigue life, английский
- The theoretical number of revolutions (or hours of operation) a bearing will last under a given constant load and speed before the first evidence of fatigue develops on one or more of the components.
- The number of cycles of loading of a specified character that a given specimen of material can sustain before failure occurs; a measure of the useful life of the material.
- The number of cycles of stress than can be sustained prior to failure for a stated test condition.
Fatigue life (n), английский
Fatigue life:, английский
The predicted period of time to cause fatigue failure under the application of the design spectrum
Fatigue limit, английский
- The stress below which a material can be applied cyclically for an infinite number of times without failure.
- The maximum stress below which a material can presumably endure an infinite number of stress cycles. if the stress is not completely reversed, the value of the mean stress, the minimum stress or the stress ratio should be stated.
Parameters, английский

Occurrence, английский
- In insurance terminology, an accident or a continuous exposure to conditions which result in injury or damage, provided the injury or damage is neither expected nor intended. ocher, ochre a naturally occurring yellowbrown hydrated iron oxide; used as a pigment in paint and a filler in linoleum. oct on drawings, abbr. for “octagon.”
- Something that takes place neuralgia is a common occurrence after shingles. ocd ocd abbr obsessive-compulsive disorder
Standardized, английский
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].
