NON-DESTRUCTIVE TESTING METHOD AND APPARATUS FOR FLEXURAL STRENGTH OF FINE CERAMICS, AND STORAGE MEDIUM

摘要

Provided are a non-destructive testing method and apparatus for the flexural strength of fine ceramics, and a storage medium. The method comprises: adjusting an unclipped complete fine ceramics sample to an ultrasonic testing position and fixing same; adjusting an ultrasonic testing instrument, controlling and adjusting the position of an ultrasonic testing probe of the ultrasonic testing instrument until the ultrasonic testing probe, the fine ceramics sample and a resilience direction are on the same plane, performing ultrasonic testing on the sample, and collecting ultrasonic testing data of the sample; adjusting the position of the fine ceramics sample until a resilience measuring bar and the sample are on the same plane, fixing the sample, performing resilience testing on the sample, and collecting resilience testing data of the sample; and establishing a data model according to the ultrasonic testing data and the resilience testing data or substituting the ultrasonic testing data and the resilience testing data into a pre-established data model, and obtaining flexural strength characterization data of the sample. In the method, non-destructive testing is directly performed on uncut and unclipped complete fine ceramics, thereby improving the accuracy of obtained data, and realizing the reuse of a sample.
