Abstract

Residual stresses, created in a steel beam by elastic-plastic bending, are predicted using an approximate analysis and the finite element method. The predictions are compared to experimental measurements obtained from the application of incremental centre hole drilling, deep hole drilling and neutron diffraction methods. Finite element simulations of the incremental centre hole drilling and deep hole drilling methods applied to the predicted residual stresses permitted an assessment of their ability to reconstruct the stresses. An analytical reconstruction analysis using an Airy stress function together with boundary and equilibrium conditions is developed and applied to the predictions and measurements. The reconstruction of the predictions enabled a reference case to be developed and used to assess the application of the reconstruction process to experimental data. It is shown that satisfactory through depth residual stress profiles can be obtained, providing the errors are about the same of those found in the measurement techniques.
