The perforated plate has strain concentration near the holes, and failure initiates from this point after fatigue and creep damages. Thus, the accurate estimation procedure is required to obtain strain amplitude under repeated loading histogram at elevated temperature. The stress locus method proposed by Kasahara and Shimakawa is based on elastic creep analysis. where the almost same stress-strain locus was obtained for typical nuclear plants. The present paper describes the mechanical feature of plate with holes to obtain this stress-strain locus from elastic plastic analysis. This locus depends on the geometry and loading condition of the problem leading to the introduction of inelastic analysis in design procedure.
