Industrial Physics’ companies have been in the testing game for a long time…and we’ve learnt a great deal about elongation testing.
Our highly accurate testing devices offer insightful information on how far a sample will stretch before it breaks. The result is typically normally expressed as a percentage, also known as percent elongation (% elongation).
It’s important you know your gauge length to carry out critical and accurate elongation calculations. This consists of two measurement points: the first is the starting distance between the upper and lower grip edges; the second is the distance travelled by the grips when the sample breaks. Elongation is calculated by dividing the distance travelled by the original gauge length.
