PROBLEM TO BE SOLVED: To accurately predict development of cracks when an object is destroyed without performing a destruction test.SOLUTION: A fragile factor detection unit 22 detects a fragile factor part representing the most fragile factor defined for an object in advance from a photographed image of tissues of the cross section of the object. A crack prediction unit 24 predicts development of cracks on the cross section when the object is destroyed by a load being applied in a load application direction from an input crack starting point on the basis of the input load application direction and a distance and direction between the detected fragile factor parts. |
