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-ax i symmetric residual stresses in cylindrical components. The new procedure uses a Fourier series to represent the residual stresses. This paper descri bes an experimental application of the procedure to measure the residual st resses around a hole in a specimen subjected to a uniaxial overload. Good a greement is found between the measured residual stresses and those predicte d using a finite element simulation. (C) 2001 Elsevier Science Ltd. All rig hts reserved.
