Translation is the process by which the genetic code contained within a messenger RNA (mRNA) molecule is decoded to produce a specific sequence of amino acids in a polypeptide chain.It occurs in the cytoplasm following DNA transcription and, like transcription, has three stages: initiation, elongation and termination. Let's try to keep this as simple as possible. A good way to analyze the behavior of a material during its deformation is using the stress-strain curve. Elongation definition and meaning Elongation What Does Elongation Mean? This point represents the separation between elastic behavior and plastic behavior and, once reached, the material does not return to its original size and shape. The . Delivered to your inbox! Percent elongation is a measurement that captures the amount a material will plastically and elastically deform up to fracture. The mechanical properties of materials indicate how they behave when a material is subjected to external forces, such as tension and compression forces. It is obtained from a test on a specimen subjected to uniaxial tension. Elongation. Kanwarjot Singh is the founder of Civil Engineering Portal, a leading civil engineering website which has been .

The elongation phase occurs in the plastic region, after the yield point. This happens because the atoms that constitute the materials are submitted to distances that break their bonds. - Definition, Equation & Example, What is Internal Friction? It is the slope of the stress-strain curve up . It is elastic; because of this property a rubber band can be stretched to 9 or 10 times its original length and when the load is removed it regains its original length. After the yield point, the same material will find itself in the plastic region, where its deformation is now irreversible. 2. something that is elongated; prolongation.

Percentage elongation measures the length that a metal deforms as a percentage of its original length, after it is pulled to failure during a tensile test. To better understand the concepts presented so far, one can use the stress-strain curve of a material. Tolerances can apply to many different units. In this context, when studying the deformation of materials, one must consider that a material subjected to external forces can be in two distinct regions of behavior: The elastic behavior is observed in the region where the stresses are lower than the yield point value.
