摘要： This invention is to provide a method and a system which, by making use of a stress luminescent material, renders it possible to directly observe a stress distribution on the base of a real time without electrical contacts, and to easily measure a stress or a stress distribution and a stress image. Essentially, the invention comprises the steps of adding a stress to a tested body containing a stress luminescent material whose light emission is proportional to the stress, making visually observable a stress distribution over the tested body in accordance with a luminous intensity of the stress luminescent material contained in the tested body, measuring the luminous intensity of the luminescent material of the tested body, comparing the measured value of the luminous intensity with certain correlation data indicating a relationship between the luminous intensity of the stress luminescent material and a stress, thereby obtaining a stress value or a stress distribution over the tested body.

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.

摘要： A stress-induced light emitting composite material according to the present invention contains at least stress-induced light emitting inorganic particles, which emit light at application of a mechanical effect thereon and a polymer material. The stress-induced light emitting inorganic particles are not more than a wavelength of visible light in particle diameter and surface-treated. With this arrangement, the stress-induced light emitting composite material becomes transparent in a visible light range. Moreover the surface treatment of the stress-induced light emitting inorganic particles give water resistance to the stress-induced light emitting inorganic particles.
