stress raiser

stress raiser

[′stres ‚rā·zər]
(metallurgy)
A notch, hole, or other discontinuity in contour or structure which causes localized stress concentration.

stress raiser

stress raiser
A stress raiser on a propeller. A nick of this size means that the propeller will need to be either discarded or sent back to the manufacturer.
A sharp nick on a propeller. It is so called because the stresses can be concentrated on the point of the nick, possibly causing the structural failure or the loss of a propeller tip, extreme vibration, and loss of control.

The stress variation in the area of the stress raiser is shown in Fig.
The sharp corner on the casting is a stress raiser that cracked on machining.
The resilient middle layer absorbs the bending force, reducing stress raisers, which can break the outer layer, ensuring the anti-corrosion inner layer is well protected (Figure 5).
Solution Accuracy: Improved mesh quality around critical boundaries and stress raisers with a new quadrilateral element meshing option.
Stress raisers are frequently a preferred site for fracture origin, particularly in fatigue.
Stress raisers in design should be avoided to reduce the possibility of fracturing.
The splitting was caused by large slag inclusions acting as stress raisers.
Since this specimen does not have a cut edge, it doesn't have stress raisers at its edge like the cut edge of a tensile specimen.
These include a new Quadrilateral Element meshing option for critical boundaries and stress raisers, a Nastran Spot Weld Element for sheet metal, a Macro-driven program file for automating repetitive tasks, and a fully integrated BASIC development environment for customizing post-processing functions.
a fully integrated BASIC development environment, providing direct access to the OLE/COM API of Femap, as well any other OLE/COM- compliant application; * an updated macrodriven program file environment, with its own access window provides record, editing and playback functionality for the automation of repetitive tasks; * strengthened NX Nastran integration with a new linear surface-to- surface contact capability; * improved mesh quality around critical boundaries and stress raisers with a new quadrilateral element meshing option; * improved results visualization and collaboration with a new option to directly output JT files; and * support for Nastran spot weld elements to aid modeling of sheet metal component fasteners.
Shearing and plug flow again are the reasons for the formation of the bands of defects, and the position of the stress raisers and the resulting velocity profile explain the location of the band.
