Ultrasonography

4.6K
Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.
During an ultrasonography procedure, a handheld device called...

Area of Science:

  • Materials Science
  • Non-Destructive Testing
  • Composite Materials

Background:

  • Porosity significantly impacts composite laminate mechanical behavior and service life.
  • Accurate evaluation of porosity is crucial for quality control and material performance prediction.
  • Nonlinear ultrasonics offer high sensitivity for detecting small defects like porosity.

Purpose of the Study:

  • To develop and present an advanced imaging method for visualizing the porosity field in composite materials.
  • To evaluate the effectiveness of two novel nonlinear ultrasonic techniques for porosity assessment.

Main Methods:

  • Utilized nonlinear ultrasonic techniques employing backscattered signals from a phased array system.
  • Method 1: Analyzed half-harmonic frequency components from microbubble reflections.
  • Method 2: Calculated the frequency derivative of the attenuation coefficient, correlating it with porosity content.

Main Results:

  • Both proposed nonlinear ultrasonic methods demonstrated high accuracy in porosity evaluation compared to traditional C-scan.
  • The attenuation coefficient method showed superior accuracy in defining bubble shapes, especially when surface effects were minimal.
  • The techniques successfully imaged the porosity field in experimental composite samples.

Conclusions:

  • Nonlinear ultrasonics provide a highly accurate and sensitive approach for porosity imaging in composites.
  • The developed methods enhance quality control and enable better prediction of material behavior under service conditions.
  • These techniques represent a significant advancement in non-destructive evaluation of composite materials.
