A new procedure based on Sachs’ boring for measuring non-axisymmetric residual stresses: experimental application

A new procedure has been developed based on Sachs’ boring to measure non-axisymmetric residual stresses in cylindrical components. The new procedure uses a Fourier series to represent the residual stresses. This paper describes an experimental application of the procedure to measure the residual stresses around a hole in a specimen subjected to a uniaxial overload. Good agreement is found between the measured residual stresses and those predicted using a finite element simulation.
