elongation

 [e-long-ga´shun]
1. the act or process of increasing in length.
2. a radiographic distortion in which the image is longer than what is being x-rayed.

e·lon·ga·tion

(ē'lon-gā'shŭn),
1. The increase in the gauge length measured after fracture in tension within the gauge length, expressed in percentage of original gauge length.
2. The lengthening of a macromolecule, for example, in the synthesis of long-chain fatty acids or in the synthesis of a protein.

elongation

[i′longā′shən]
Etymology: L, elongatio, a prolonging
a state of being lengthened or extended.

e·lon·ga·tion

(ē-long-gāshŭn)
radiology Radiographic distortion in which the image appears longer than it is; caused by insufficient vertical angulation.

e·lon·ga·tion

(ē-lawng-gāshŭn)

elongation (ē´lônggā´shən),

n the process or condition of increasing in length before breaking; indicates ductility (e.g., of a metal).
elongation, percent,
n 1. the increase in length of a material after fracture in tension.
n 2. a mechanical test usually employed to measure ductility.

elongation

1. in protein synthesis, cyclic process of growth of a polypeptide chain from mRNA attached to ribosomes. Requires mRNA, ribosomes, activated aminoacyl-tRNA, elongation factor EF-Tu activated with GTP.
2. in fatty acids, a process of adding carbon from acetyl CoA to a lengthening acyl chain. Mechanism for achieving diversity of fatty acids in biological systems.

elongation factor
one in a group of proteins involved in the elongation of polypeptide chains during protein synthesis.

In the case of 10 wt% PLA-g-NR having MNR10, the loading of PLA-g-NR into PLA resulted in a 200% improvement in impact strength and twofold percent elongation at break (flexibility) In the case of MNR with higher anhydride content (MNR20), PLA/PLA-g-NR blends exhibited poorer toughness property due to the partial loss of elasticity of NR derived from a decrease in double bonds through MA grafting reaction.
It can be seen that aging does not significantly affect the percent elongation, since most materials already have low ductility.
The values of percent area reduction and percent elongation are key indicators of a material's ductility at controlled loading rates.
With its excellent adhesive, elasticity and temperature-resistant properties, including a minus 18 degree to a 105 degree C functional range, and 250 percent elongation, it is no surprise that Scotch Super 33+ Vinyl Electrical Tape from 3M is overwhelmingly preferred by professional electricians.
Percent Elongation At Break Before Ageing - 150 Percent.
3: 1, wherein the necked nonwoven substrate has a percent elongation in a cross-direction of between about 30% and about 300% and, wherein the stretchable nonwoven sheet has a thickness of 0.
Most likely, the yield strength will be reduced, and the percent elongation will increase.
General purpose PS (GPPS) with the grade name SC203EL (tensile strength ~ 47 MPa, percent elongation 5%, and specific gravity ~ 1.
Different thermoforming conditions were simulated by changing the oven temperature (related to sheet temperature), crosshead speed (related to plug speed), and percent elongation (related to depth of draw in the mold).
Additionally, PermaDri never hardens, and retains within 800 percent elongation, and as a result will not crack and allow moisture penetration, a well-known weakness of many corrosion protection coatings" Pressutti said.
If the theory holds, the percent elongation to break would decrease with additional thermal cycling as the chemical crosslinks rupture with exposure to the extremes.
The development of cellulose plastic as a matrix polymer in bio-composites requires that properties such as percent elongation, flexibility and impact behavior be tailored to meet the needs of the application.
