Ultrasonic Testing Achieves 2.69% Error for Elastic Modulus of Soda-Lime Glass

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

How to apply

Implement ultrasonic testing for incoming material inspection of glass, and explore advanced signal processing or calibration techniques for ceramic components where precise elastic modulus data is critical.

Project actions

01When choosing a testing method, consider the material's homogeneity and the required accuracy.
02Document all material properties, including density and porosity, as they can influence test results.

Method & Evidence

AimCan ultrasonic testing accurately determine the elastic modulus of structural ceramics and glass, and how does probe frequency affect accuracy?

MethodComparative experimental study

ProcedureUltrasonic testing was performed on soda-lime glass and ceramic tiles using probes of 1, 2, and 4 MHz. Density and porosity were also characterized. The elastic modulus determined by ultrasonic testing was compared to results obtained from traditional bending tests.

ContextMaterials science, manufacturing quality control

Variables

IVProbe frequency (1, 2, 4 MHz)

DVElastic modulus, Error percentage relative to bending test

CVMaterial type (soda-lime glass, red ceramic tile, white ceramic tile), Density, Porosity

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.
