Research results of damage and failure of unidirectional laminate packages under tension are presented. A study of the kinetics of damage and failure of the laminate structure is carried out by means of acoustic emission (AE) and synchronous video recording. The conformity between failure proceses occurring on the microscopic, mesoscopic and macroscopic scale levels and the recorded AE events including their energy parameters, shape and spectrum is established. The structural–phenomenological approach implemented by dividing the AE data array into energy clusters allows analyzing the degree of damage and failure of the material employing new criteria parameters, namely the registration activity and the weight content of the location AE events in the clusters of the lower, middle and upper energy levels.

声发射结合视频记录对单向层压板的损坏和破坏

给出了单向层压包装在拉伸下的破坏和失效的研究结果。通过声发射(AE)和同步视频记录对层压结构的破坏和破坏动力学进行了研究。建立了在微观,介观和宏观尺度上发生的失效过程与所记录的AE事件(包括其能量参数,形状和光谱)之间的一致性。通过将AE数据阵列划分为能量簇而实现的结构-现象学方法允许使用新的标准参数来分析材料的破坏和破坏程度,即下层的簇中的注册活动和位置AE事件的权重,中高能量水平。
