The answer depends on what causes the elongation: a stretching force (tension) or thermal expansion.
To calculate percent elongation with an equation: [(final length - initial length) / initial length] x 100 = percent elongation On a graph - To calculate percent elongation, draw a line to the x-axis from the point of fracture parallel to the straight line part of the graph. The extension at this point is then divided by the gauge length.
It means the material is very ductile!!
as a percentage of what.
Percentage is considered a singular noun: The percentage of unemployed citizens is usually about five percent.
On base percentage plus slugging percentage
what is the full form of hscrm
They each refer to different grades of steel.The reinforcement steel bars used in RCC (Reinforced Cement Concrete) are designated into grades as Fe415 or Fe500 depending on their Yield Strength.The numbers 415 and 500 tell about this Yield Strength in N/mm2 the bars are designed and manufactured to have.Differences between 'Fe415 steel' and 'Fe500 steel':Fe415 has a minimum Yield Strength of 415 N/sq.mm and Fe500 has a minimum Yield Strength as 500 N/sq.mm.The minimum Ultimate Tensile Strength (UTS) of is 485 N/mm2 and that of Fe500 is 545 N/mm2.The minimum Percentage Elongation for Fe415 is 14.5 and that of Fe500 is 12.

find it out . It's measured in the lab after a pull test. Steel elongation can be measure manually or using device called extentiometer. To measure elongation of steel manually we must give 2 punch marks on the specimen with specified length (see standard/code such as ASTM, ASME etc for specimen shape and size) addressed L0. After a pull test (tension/tensile test) we measure the distance between that 2 punch marks and addressed L1. Thus, the elongation of the specimen in percentage is ((L1-L0)/L0) x 100%. Measure elongation using extentiometer is lot more easier because we can directly read the result. But this method limited for small elongation measurement only.
You use calipers or a micrometer.
Letters. The probable reason for using those particular ones is that Fe is the chemical symbol for iron.
The abbreviationFe stands for Ferrous material ie iron from which the reinforcement steel bars are manufactured.The reinforcement steel bars used in RCC (Reinforced Cement Concrete) are designated as Fe415 or Fe500 depending on their Yield Strength. (The numbers 415 and 500 tell about this Yield Strength in N/mm2 the bars are designed and manufactured to have.)As per IS : 1786 Yield Stress (also known as 0.2%proof stress) of Fe 500 is 500 N/mm2.So, Fe500 steel means the reinforcement steel rods (or bars) that can safely withstand an Yield Stress of 500 N/mm2.
The abbreviation Fe stands for Ferrous material ie iron from which the reinforcement steel bars are manufactured.The reinforcement steel bars used in RCC (Reinforced Cement Concrete) are designated in grades of Fe250, Fe415 or Fe500 depending on their Yield Strength.(The numbers 215, 415 and 500 tell about this Yield Strength in N/mm2 the bars are designed and manufactured to have.)Fe415 indicates that the Yield Strength (tensile strength when it is subjected to elongation) of steel is 415 N/mm2.

Elongation is the percentage of the final dimension relative to the initial dimension. For instance; A 1m length of metal is put under a load and is stretched to a final length of 1.5m The elongation of this is 150% because the final length is 150% of the initial length.
