Abstract

A combined system of four beams moire interferometer and incremental hole-driling machine was designed and applied for residual stress measurement. Two typical experiments were done using this system: non-uniform in-depth residual stress measurement of an ultrasonic shot-peening Aluminum plate; non-uniform in-plane residual stress measurement of an elastic-plastic Aluminum bent beam. Experiments results show good accordant with other measurement results and theory analysis results.
