PROBLEM TO BE SOLVED: To provide a method of determining wrinkles that is capable of correctly determining whether there are wrinkles from a result of shaping analysis of a sheet-like base material, as well as efficiently designing shape molding conditions and a shape of the base material.SOLUTION: A method of determining wrinkles includes the steps of: analyzing shaping by calculating a shape of a sheet-like base material after shaping with a finite element method; and determining wrinkles by calculating overlap length of the sheet-like base material that is sequentially calculated in the step of analyzing shaping and/or overlap length of the sheet-like base material in a state after shaping acquired in the step of analyzing shaping, as an evaluation index.SELECTED DRAWING: Figure 1 |
