Stress analysis method of the piping, and, stress analysis device

摘要

PROBLEM TO BE SOLVED: To provide a method of analyzing stress on a piping capable of precisely analyzing stress on a piping through which a heated medium flows, and a stress analyzer for carrying out the method.;SOLUTION: According to an aspect of the disclosure, a method of analyzing stress on a piping includes the steps of: setting analysis conditions on the basis of design information (S101-102); measuring outer dimensions and shapes in the cold state (S103); optimizing the analysis conditions so that the differences between design values obtained from the analysis conditions and measured values are within threshold values (S104); and carrying out the stress analysis based on the optimized analysis conditions (S110).;COPYRIGHT: (C)2015,JPO&INPIT
