Characterization of Concrete Hole Defects by Ultrasonic Finite Amplitude Method

  • 摘要: 超声有限幅度法是用超声波在受损材料中传播时产生的高次谐波与材料非线性参数的关系, 来检测材料损伤的方法, 其在材料的微观损伤检测中已有较成熟的应用。用有限幅度法检测含有不同大小孔洞缺陷的混凝土试块, 检测结果表明, 非线性参数能反映出混凝土孔洞缺陷的大小。
    Abstract: The finite amplitude method is a nonlinear ultrasonic technique that uses the relation of higher order ultrasonic harmonics with nonlinear parameters of damaged materials and structures for the characterization of material defects, which has been more often used in material microscopic damage diagnostics. The finite amplitude method is used in detecting concrete with different sizes of holes. The results show that the nonlinear parameter can sensitively reflect the extent of the hole defect.
