PROBLEM TO BE SOLVED: To provide a criterion analysis method, a program and a system capable of ensuring accuracy without performing two or more hole expansion tests. SOLUTION: The fracture criteria analysis method is to acquire the hole expansion test data obtained in the hole expansion test of a metal material (S1), to acquire the tensile test data obtained in the tensile test of a metal material (S2). To determine the fracture limit strain based on the hole expansion test and the strain gradient based on the hole expansion test (S3) using the hole expansion test data, and to determine the fracture limit strain based on the tensile test using the tensile test data. (S4), the fracture limit strain based on the hole expansion test, the strain gradient based on the hole expansion test, and the fracture limit strain based on the tensile test are used to generate fracture criterion data showing the relationship between the strain gradient and the fracture limit strain. To do (S5). [Selection diagram] FIG. 8
