Correct design and usage of the measuring chain is very important for successful measurement and the accurate data acquisition. Therefore it is sufficient to pay adequate attention to this problem before the experimental testing itself. http://pubs.sciepub.com/ajme/1/7/32/ajme-1-7-32.pdf residual stressesRing-Core methodmeasuring chain
