本研究旨在探讨人体软组织(前十字韧带)断裂时的声发射(AE)与其破坏机制之间的关系。累积的声发射活动突出了严重损伤的开始，而其他参数则显示出重复的趋势，与组织的机械行为很好地相关。在整个实验过程中，声发射信号的频率成分有所增加，而其他指标则表现在不同的故障模式之间。初步研究结果表明，声发射技术可以揭示前交叉韧带组织的破坏过程，为前交叉韧带重建提供有用的数据。(C)2011年美国声学学会
The scope of this study is to relate the acoustic emission (AE) during rupture of human soft tissue (anterior cruciate ligament, ACL) to the mechanisms leading to its failure. The cumulative AE activity highlights the onset of serious damage, while other parameters, show repeatable tendencies, being well correlated with the tissue's mechanical behavior. The frequency content of AE signals increases throughout the experiment, while other indices characterize between different modes of failure. Results of this preliminary study show that AE can shed light into the failure process of this tissue, and provide useful data on the ACL reconstruction. (c) 2011 Acoustical Society of America
