Paper Abstract

The Interferometric Strain/Slope Rosette (ISSR) is combined with ring-core method to measure residual stresses. The method has many advantages such as non-contacting and short gage-length compared with resistance strain rosette/ring-core method. The ISSR measures the relived strains during ring-core cutting. A finite element model is set up to calculate residual stresses. Two experiments are conducted on an aluminum plate to determine the residual stresses induced form its manufacturing processes. The residual stress distributions with depth are measured by using incremental ring-core cutting around an ISSR.
