For all notch types, a key parameter in governing stress concentration and failure in notched materials is the notch tip curvature or radius. [ 1 ] Sharp tipped V-shaped notches are often used in standard fracture toughness testing for ductile materials, polymers and for the characterization of weld strength.
Bicycle frame in steel tube, notched at the joints before TIG welding or brazing. Tube notching is commonly performed before joining light-gauge tubes to make a tee or similar joint, as by welding. Either one or both tubes may be notched before assembly. A familiar example of tube notching is in the manufacture of bicycle frames.
The notched lapel (American English), step lapel or step collar (British English) is sewn to the collar at an angle, creating a step effect. This is the standard on single-breasted suits, and is used on nearly all suit jackets, blazers, and sports jackets. The notched lapel double-breasted jacket is a rare setting. [6]
Crenation (from modern Latin crenatus meaning "scalloped or notched", from popular Latin crena meaning "notch") [1] in botany and zoology, describes an object's shape, especially a leaf or shell, as being round-toothed or having a scalloped edge.
A notched sample is generally used to determine impact energy and notch sensitivity. The test is similar to the Charpy impact test but uses a different arrangement of the specimen under test. [ 1 ] The Izod impact test differs from the Charpy impact test in that the sample is held in a cantilevered beam configuration as opposed to a three-point ...
Notched box plots apply a "notch" or narrowing of the box around the median. Notches are useful in offering a rough guide of the significance of the difference of medians; if the notches of two boxes do not overlap, this will provide evidence of a statistically significant difference between the medians.

Two different ways of marking cut-out records on LP jackets. When LPs were the primary medium for the commercial distribution of sound recordings, manufacturers would cut the corner, punch a hole, or add a notch to the spine of the jacket of unsold records returned from retailers; these "cut-outs" might then be re-sold to record retailers or other sales outlets for sale at a discounted price.
Notch signalling pathway, a cell signalling system present in most multicellular organisms; Notch proteins, a family of transmembrane proteins; Notch filter, a band-stop filter with a narrow stopband; Notch test, also known as Charpy impact test; Lion Notch, a male lion featured in the nature documentary series Big Cat Diary
