METHOD AND SYSTEM OF IDENTIFYING A BOND BOUNDARY BETWEEN A SOUND BOND AND A WEAK BOND IN A MULTILAYER ARTICLE

A method of identifying a bond boundary between a sound bond and weak bond in a multilayer article may include determining a plurality of positions on a surface of the article; for each position of the plurality of positions, obtaining a full-wave, time domain waveform of ultrasonic waves reflected from the article; and, for each pair of adjacent positions among the plurality of positions, determining whether there is a bond boundary between a first position and a second position based on a comparison of a waveform characteristic of a first waveform generated at the first position and the waveform characteristic of a second waveform generated at the second position; and in response to a determination that there is a bond boundary between the first position and the second position, determining a boundary position based on the first position and the second position and memorializing the boundary position. 一种识别多层制品中健全结合和薄弱结合之间结合边界的方法可包括：确定制品表面上的多个位置；对于所述多个位置中的每个位置，获得从所述制品反射的超声波的全波时域波形；以及对于所述多个位置中的每一对相邻位置，基于在该对相邻
