PRESSURE VESSEL EVALUATION APPARATUS AND PRESSURE VESSEL EVALUATION METHOD

摘要

PROBLEM TO BE SOLVED: To shorten the time required for evaluating strength of pressure vessels based on a stress analysis and to increase the accuracy of evaluation.;SOLUTION: Three-dimensional data on a pressure vessel is input. A heat conduction analysis and an elasto-plastic analysis are performed on the pressure vessel by a finite element method according to the input three-dimensional data, material data stored in a material data storage part and analysis conditions stored in an analysis condition storage part. Whether or not the pressure vessel satisfies standardized pressure vessel standards which define evaluation based on an analysis result of three-dimensional data is evaluated according to the analysis results. The evaluation result is then output.;COPYRIGHT: (C)2010,JPO&INPIT
