摘要： This damage evaluation device (1) comprises a phased array probe (11) that emits an ultrasonic signal from the surface of inspection metal (22) toward the inside of the inspection metal (22) and detects reflected signals reflected from a prescribed area (Q1) inside the inspection metal (22), and a computation processing unit (14). The computation processing unit (14) sets a plurality of planes (qn) parallel with one another in the inspection area (Q1), calculates pixel data by quantifying the reflected signals from segments set in each of the planes (qn), calculates the degree of deviation of the pixel data, and evaluates damage to the inspection metal (14) on the basis of the degree of deviation.

摘要： An object of the present invention is to quantitatively evaluate a distribution of defects which are generated within an inspection material. In order to achieve this object, the present invention provides a defect inspection apparatus comprising: an ultrasonic wave probe; an ultrasonic wave transmitting and receiving device that irradiates ultrasonic waves via the ultrasonic wave probe onto a surface of an inspection material on which a predetermined propagation medium has been provided, and that also receives as noise signals ultrasonic waves that have been scattered by defects present in the interior of the inspection material; a frequency spectrum calculation device that performs time division on the noise signals so as to divide them into time widths that correspond to positions in the depth direction of the inspection material, and calculates a frequency spectrum for each one of the time-divided noise signals; and a defect distribution detection device that, based on the frequency spectrums, calculates values showing a level of defect progression corresponding to a position in the thickness direction of the inspection material.

摘要： In the present invention, a current can be made to flow in a conductive composite material by placing a coil 7 at a position facing the conductive composite material, thereby eliminating the need of work and so forth for affixing an electrode to the conductive composite material. As a result, disorder in the arrangement of fibers in the conductive composite material can easily be detected. Provided is a method for detecting meandering of fibers in a conductive composite material, the method including a step for placing a magnetic field sensor 8 at a position facing a surface Sa of a conductive composite material such that a magnetosensitive axis direction of the sensor is horizontal along the surface Sa and is parallel to a coil surface 7e. Therefore, a part where the arrangement of fibers is disordered in the conductive composite material can be detected by measuring the magnetic field with the magnetic sensor 8.
