<title>plication of Acoustic Emission Technique in Detecting Mechanic Performance of Particleboard

在刨花板三点弯曲试验中运用声发射(AE)技术对其力学性能作了检测,采用AE参数和载荷-位移曲线相结合的方法对刨花板在受力变形损伤过程中的AE特征进行了分析和研究,并对损伤机理进行了分析。结果表明,AE技术可作为检测刨花板力学性能的补充手段。

<abstract> three point bending experiment of particleboard,applying acoustic emission technique to detect its mechanic performance. Adopting the method of combining AE parameter with load-displacement curve to study the AE characteristics in deformation and to analyze the damage mechanism. Experiment results show that AE technique can be used as a supplemental method to detect mechanic performance of particleboard.
