Discontinuity, английский
- Разрывность (течения, кривой)
- Разрыв (непрерывности); нарушение сплошности; перегиб кривой; разрезность {конструкции) о ~
- [stratigraphy] any interruption in sedimentation, whatever its cause or length, usually a manifestation of nondeposition and accompanying erosion; an unconformity. gg part 629 - glossary 629-24 (430-vi-nssh, 2008)
- An interruption in the normal physical structure or configuration of a part such as cracks, laps, seams, inclusions, porosity. a discontinuity may or may not affect the usefulness of a part. see defect.
- Interruption in the physical structure or configuration of a test object. after nondestructive testing, a discontinuity indication may be interpreted to be a defect. compare defect; indication. discontinuity, artificial: reference discontinuity such as hole, indentation, crack, groove, or notch introduced into a reference standard to provide accurately reproducible indications for determining test sensitivity levels.
- Interruption in the physical structure or configuration of a test object. after nondestructive testing, a discontinuity indication can be interpreted to be a defect.4,7 compare defect; indication. discontinuity, artificial: reference discontinuity such as hole, indentation, crack, groove or notch introduced into a reference standard to provide accurately reproducible indications for determining test sensitivity levels.4 discontinuity, inherent: material anomaly originating from solidification of cast metal. pipe and nonmetallic inclusions are the most common inherent discontinuity and can lead to other types of discontinuities in fabrication.2,5 discontinuity, primary processing: discontinuity produced from the hot or cold working of an ingot into forgings, rods, bars and other shapes.2,5 discontinuity, secondary processing: discontinuity produced during machining, grinding, heat treating, plating or other finishing operations.2,5 discontinuity, service induced: discontinuity caused by the intended use of the part.
- Intentional or unintentional interruption in the physical structure or configuration of a part.1,4 after nondestructive testing, unintentional discontinuities interpreted as detrimental in the host object may be called flaws or defects. compare defect, dislocation and indication.1 discontinuity, artificial: reference discontinuities such as holes, indentations, cracks, grooves or notches that are introduced into a reference standard to provide accurately reproducible indications for determining sensitivity levels.1 discontinuity, primary processing: in metals processing, a material anomaly produced from the hot or cold working of an ingot into forgings, rod and bar.1 discontinuity, service induced: material anomaly caused by the intended use of the part.1 display resolution, thermal: precision with which an instrument displays its assigned measurement parameter (temperature), usually expressed in degrees, tenths of degrees, hundredths of degrees and so forth.3
- Interruption in the physical structure or configuration of a test object. after nondestructive testing, a discontinuity indication may be interpreted as a defect. compare anomaly; defect; indication. drift (electronic): change in output reading of an instrument, usually due to temperature change.
- Interruption in the physical structure or configuration of a test object. after nondestructive testing, a discontinuity indication may be interpreted as a defect. compare anomaly; defect; indication. discontinuity, artificial: reference anomaly such as hole, indentation, crack, groove, or notch introduced into a reference standard to provide accurately reproducible indications for determining test sensitivity levels. see also known discontinuity standard. discontinuity, inherent: material anomaly originating from solidification of metal. pipe, banding, and nonmetallic inclusions are the most common inherent discontinuities and can lead to other types of discontinuities in fabrication. discontinuity, primary processing: discontinuity produced from the hot or cold working of an ingot into forgings, rods, bars, and other shapes. glossary d-e 497 discontinuity, secondary processing: discontinuity produced during machining, grinding, heat treating, plating, or other finishing operations. discontinuity, service induced: discontinuity caused by the intended use of the part. see also brittle crack propagation; creep; ductile crack propagation; fatigue crack propagation.
- Interruption in the physical structure or configuration of a test object. after nondestructive testing, a discontinuity indication can be interpreted to be a flaw or a defect.10 compare defect; indication.5,6 discontinuity, artificial: reference discontinuity such as hole, indentation, crack, groove, or notch introduced into a reference standard to provide accurately reproducible indications for determining sensitivity levels.4
- Interruption in the physical structure or configuration of a test object. after nondestructive testing, a discontinuity indication can be interpreted to be a flaw or a defect.10 compare defect; indication.

Initial permeability, английский
- Slope of the induction curve at zero magnetizing force as the test specimen begins to be magnetized from a demagnetized condition (slope at the origin of the b,h curve before hysteresis is observed).
- Slope of the induction curve at zero magnetizing force as a test object begins to be magnetized from a demagnetized condition (slope at the origin of the bh curve before hysteresis is observed).4
Infrared thermography, английский
- Imaging of a temperature field through the emitted infrared radiation. see infrared radiation. compare thermography.
- Imaging of a temperature field through the emitted infrared radiation. thermography uses an instrument or system that displays infrared radiant energy from a target surface on a thermal map, or thermogram, where color hues or gray shades can be related to the temperature distribution on that surface. see infrared radiation.
