  • PS02 Study on error factors in strain measurement by DIC for tensile test of flat plate with multiple holes made by laser processing

抄録

In the strain measurement under tensile testing by digital image correlation (DIC) method, the error factors were investigated including sprayed texture, laser processing and chucking. It was shown that the density of sprayed texture was influential on the strain value. Instead of providing texture manually, a spraying apparatus was developed, which could provide higher quality texture for DIC measurement. Finally, the influence of uncertainty parameters including size and location of holes, specimen width and chucking length was investigated numerically. The stepwise limited sampling (SLS) method could predict a possible high stress value by a pair of many uncertainty parameters.
