Material Testing for Determining Vibration Energy Attenuation Properties of Materials – Damping Loss Factor

Test method for Determining the Vibration-Damping Properties of Materials – Damping Loss Factor helps control vibration, control quality during the production process, and optimize the research and development of damping materials.

Overview of the Test Method for Determining the Vibration-Damping Properties of Materials – Damping Loss Factor

Test method name: Standard test method for determining the vibration-damping properties of materials – Damping Loss Factor.

Test method: ASTM E756-05: Standard Test Method for Measuring Vibration – Damping Properties of Materials [1]

Performed at: Laboratory, Institute of Acoustic Materials Development & Application (DASM).

1. Objectives and test subjects

– Objective

This test method measures the vibration-damping characteristics of materials: loss factor (η) and Young's modulus (E) or shear modulus (G). Accurate over a frequency range of 50 to 5000Hz and over the useful temperature range of the material, this method is useful in evaluating materials with applications in structural vibration, building acoustics, and audible noise control.

This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

– Subject:

Materials with applications in structural vibration, building acoustics, and audible noise control such as metals, enamels, ceramics, rubbers, plastics, fiber-reinforced matrix epoxies, and wood can be formed to test cantilever beam specimen configurations.

2. Experimental procedure

The experimental procedure uses an impedance tube.

Execution steps:

• Prepare all equipment and test specimens thoroughly.
• Perform specimen measurement.
• Process and report the results.

3. Notes

Test specimens consist of 3 types:

• Self-supporting damping materials are evaluated by forming a single, homogeneous test beam from the damping material itself.
• Non-self-supporting damping materials are evaluated for their extended damping characteristics in a two-step procedure.
• Measuring the shear damping characteristics of non-self-supporting damping materials.

Role – importance of the Test Method for Determining the Vibration-Damping Properties of Materials – Damping Loss Factor

Determining the Vibration-Damping Properties of Materials – Damping Loss Factor performed by the Institute of Acoustic Materials Development & Application helps meet practical needs such as:
