Information processing apparatus, information processing method, and program

An information processing method performed by a processor, the information processing method comprising:

• creating a shape model expressing a structure to be analyzed, the structure being composed of a plurality of different kinds of materials and the shape model being composed of a plurality of different mesh types, wherein respective ones of the plurality of different mesh types correspond to respective ones of the plurality of different kinds of materials;
• extracting a crack leading edge candidate from the shape model after progress of a crack in the structure;
• calculating an elastic energy release rate that indicates an elastic energy released when the crack progresses to the extracted crack leading edge candidate;
• and
• deciding a crack leading edge after the progress of the crack at least based on the elastic energy release rate,
• wherein the crack leading edge candidate that satisfies a predetermined condition is extracted from among crack leading edge candidates obtained in terms of the shape model.

A non-transitory computer-readable medium storing instructions that, when executed by a processor of a computer, cause the computer to perform operations comprising:

• creating a shape model expressing a structure to be analyzed, the structure being composed of a plurality of different kinds of materials and the shape model being composed of a plurality of different mesh types, wherein respective ones of the plurality of different mesh types correspond to respective ones of the plurality of different kinds of materials;
• extracting a crack leading edge candidate from the shape model after progress of a crack in the structure;
• calculating an elastic energy release rate that indicates an elastic energy released when the crack progresses to the extracted crack leading edge candidate;
• and
• deciding a crack leading edge after the progress of the crack at least based on the elastic energy release rate,
• wherein the crack leading edge candidate that satisfies a predetermined condition is extracted from crack leading edge candidates obtained in terms of the shape model.
