Abstract

To improve a calculation technique of a fracture rate of a material.SOLUTION: A fracture rate calculation method includes an acquisition step for acquiring three-dimensional point group data of a fracture shape of a material having a vertical fracture when a direction perpendicular to a fracture of the material is regarded as a Z axis, a crack propagation direction of the material as a Y axis, and a direction perpendicular to a surface formed by a Y axis-Z axis as an X axis, a first creation step for creating shape data of a two-dimensional (X, Z) cross section and shape data of a two-dimensional (Y, Z) cross section on the basis of the three-dimensional point group data, a first extraction step for extracting a boundary point between a brittle region and a ductile region in each cross section on the basis of height information of the shape data of the two-dimensional (X, Z) cross section and the shape data of the two-dimensional (Y, Z) cross section, and a calculation step for calculating an area of the brittle region on the basis of the boundary point and calculating a fracture rate.SELECTED DRAWING: Figure 3
