| Abstract: | Residual stress is an essential tool for failure analysis and, in some cases, is the only viable means to acquire the required data on stress condition under service. The value of residual stress must be obtained by measurement and/or simulation. The methods of measurement and simulation were introduced and the role of simulation in obtaining the development and evolution of residual stress field was emphasized. Moreover, the suggestion to measure residual stress in some given cases was proposed. |
