Abstract
In order to realize application of the video extensometer in the strain hardening exponent n value testing process, to make up for the measurement range shortage of the short stroke contact extensometer. Based on the related test method of metal sheet tensile strain hardening exponent in GB/T 5028—2008, using INSTRON 5985 video extensometer to measure n5~15 value, by means of the software Bluehill 3 automatic measurement and manual measurement methods in the specified regression interval, and the simplified formula was used to verify the methods. The results showed that the n5~15 value is 0.18, which meets the requirements of the ability comparison test results.关键词
