Deregulation and privatization of once state-regulated codes and standards for power plant design and maintenance are being promoted. As a result of that, an analyst will have several options to choose the most suitable approaches from. Detailed numerical approaches, e.g. three-dimensional and/or inelastic finite element method, will be increasingly performed if appropriate. Limit analysis with the assumption of elastic, perfectly plastic body is being recognized as an effective approach to obtain a sufficiently accurate solution in pressurized equipment design and defect assessment in spite of its simplicity. The objective of this paper in to promote use of limit analysis with finite element method, showing fundamentals on how to use limit analysis in practical design and defect assessments, and how to perform an analysis along with some supporting numerical examples.
