Ultrasonic testing offers a highly accurate, non-destructive method for determining the elastic modulus of materials like soda-lime glass, with minimal specimen preparation.
AIP conference proceedings · 2018
Key Findings
- 01Ultrasonic testing yielded an elastic modulus for soda-lime glass with only 2.69% error at 2 MHz compared to bending tests.
- 02Ultrasonic testing for ceramic tiles showed significant errors (up to 41% for red, 158% for white), influenced by porosity and near-field effects.
- 03For red ceramic tiles, a 1 MHz probe showed better accuracy, but this trend was not consistent for white ceramic tiles.
Application
Design takeaway
Prioritize ultrasonic testing for homogeneous materials like glass where high accuracy is achievable, and investigate advanced techniques or calibration for more heterogeneous materials like ceramics.

Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Utilized a comparative approach with a standard testing method (bending test).
- +Investigated the influence of a key experimental parameter (probe frequency).
Limitations
The presence of internal defects or significant variations in material density can lead to inaccurate readings with ultrasonic testing.
Reliability & validity
The study's validity is supported by comparison to a standard bending test. Reliability for ceramics is questioned due to high variability in results.
Think critically
How can the 'near-field effect' and porosity be better accounted for in ultrasonic testing to improve accuracy for ceramic materials?
Design Principles
"Non-destructive evaluation methods can significantly improve the efficiency and accuracy of material property assessment in manufacturing."
For manufacturers and product developers, accurately knowing a material's elastic modulus is crucial for predicting structural performance and ensuring product reliability. Non-destructive testing methods like ultrasonics reduce material waste and speed up the quality control process compared to traditional destructive tests.
What This Means for Your Design
Using sound waves to test materials can tell us how stiff they are, working very well for glass but being trickier for materials with holes like some ceramics.

Paragraph starter
This research demonstrates that ultrasonic testing can provide a highly accurate, non-destructive method for determining the elastic modulus of materials like soda-lime glass, achieving an error rate of just 2.69%. However, the study also highlights significant challenges in applying this technique to porous ceramic materials, where factors like porosity and near-field effects can lead to substantial inaccuracies, necessitating further refinement of the methodology for such applications.
