Buzz-o-sonic has a wide range of uses, including:

• Measurement of Elastic and Damping Properties: Young's modulus, shear modulus, Poisson's ratio, and Internal Friction (Q-1)

• Quality Assurance and Quality Control: Product testing/strength prediction/defect detection...

• Statistical Process Control: Upper/Lower control limits, statistical designed experiments...

• Thermal Shock Testing: Monitor changes in properties on the same sample (see ASTM C1548)

 

See client data for some examples.

 

 

Buzz-o-sonic SAVES MONEY!

A refractories company, RHI Canada, are using Buzz-o-sonic to replace the slower, more costly cold crushing strength test (a 25% replacement for some product lines). An article describing this in more detail was published in Ceramic Industry magazine*. See our client data page for more details.

Most materials can be tested with Buzz-o-sonic

Elastic materials such as ceramics, metals and composites (including coated materials). Organic materials - polymers and wood - can also be tested, because Buzz-o-sonic measures the dynamic elastic properties at low strains.

 

Although frequency equations for impulse-excited solids are only available for simple shapes such as bars, rods, discs, tubes, rings, and plates, Buzz-o-sonic can be used to test more complex shapes. For a given size and mass, the resonant frequencies of an impulse-excited solid are often found to correlate to strength and density; and internal friction measurements often reveal defective parts. Also, a wide range of sizes can be tested. High temperature system also available. Please see our High Temperature page. We provide custom systems. Let us know your needs.
