Abstract
Residual stresses can be beneficial or detrimental to mechanical structures. In this work, a rectangular plate specimen with a cold expanded hole was designed to study the influence of these stresses on low cycle fatigue of high-strength steel. Three separated measurements of the stresses were made using different techniques: indentation method, X-ray diffraction method and contour method. The results show good agreement with finite element modelling of the cold-expanded hole problem.
