Total elongation is measured from start of deformation to start of fracture. To calculate elongation, you must first determine the length of the bar that you are stressing by, Calculate Area. % Extreme fibre elongation = 75t\Rf (1 - Rf/Ro) where. The elongation is expressed as a percentage, and is reported out to two significant figures. Percent Elongation The strain at fracture in tension, expressed as a percentage = ((final gage length initial gage length)/ initial gage length) x 100. Rather than measuring the entire length of the specimen before and after the tensile test, a gauge records the elongation over a set volume of material in the center of the test specimen. If you compare it to the basic math formula for percentage, you will notice that Excel's percentage formula lacks the *100 part.When calculating a percent in Excel, you do not have to multiply the resulting fraction by 100 since Excel does this automatically when the Percentage format is applied to a cell.. And now, let's see how you can use the Excel percentage formula on real-life data. Analytical cookies are used to understand how visitors interact with the website.
