摘要
When visualizing the stress distribution of natural bone, synthetic bone, or a member attached to either thereof without omitted points, in order to measure accurately in a variety of modes using an inexpensive system, a mechanoluminescence material thin film 6 is formed in advance on a bone material peripheral surface 5 in an appropriate area thereof including the portion where an insertion support portion 4 of an artificial hip prosthesis 2 is inserted into a hollow inside 3 of a damaged femur 1 or a synthetic bone simulating the damaged femur. The mechanoluminescence material thin film 6 portion is photographed over its entire circumference with an IICCD camera 7 from the external peripheral side thereof as or after the artificial hip prosthesis 2 is inserted. The obtained image is fed to a computer 11 to obtain a luminescence image 8. The computer 11 outputs the intensities of the received light in the form of an image as is, so that the luminescence image 8 can be obtained easily. Particularly, the data about the intensities of the received light can be used as stress/strain data virtually as is. Such method is also suitable for dynamic analysis.
