PROBLEM TO BE SOLVED: To efficiently execute the stress analysis of a structural body with a corrugation. SOLUTION: In the simple stress analysis method of corrugated structure, a structural body 1 is divided into corrugated parts 3a and 4a and a flat part 2a, the corrugated parts are formed in an anisotropic shell model, the flat part is formed in an isotropic model, and a stress analysis is made to a two-dimensional model consisting of the anisotropic shell model and the isotropic shell model by the finite element method in a method for performing the stress analysis of the structure body with at least the corrugation and the flat plate using the finite element method.
