| Outline of Final Research Achievements |
The equipment to measure the distribution of the sound pressure fictionally is invented. By measuring the sound pressure with this equipment, the following outcomes are given. 1) The method in order to determine the distribution of the impact pressure is invented. By the actual experiment, the efficiency has been confirmed. It becomes clear, that the possibility to determine the placement, space distribution and time-dependence by measuring the distribution of the sound pressure form the impacted body. 2) The method in order to determine the placement and shape of the defect in the surface of the impacted body is invented. By the present method, the placement and shape of the dent at the surface of the impacted body can be determined. Since the sound pressure can be applied to the impacted body as the impact force, the non-contact measurement of the defect should be possible.
