Test method for determining the vibration energy damping properties of materials - Poisson's ratio

Material vibration energy dissipation properties determination testing method – Poisson's ratio helps control vibration, control quality during the production process, and optimize the research and development of damping materials.

Overview of Material vibration energy dissipation properties determination testing method – Poisson's ratio

Test name: Standard test method for determining vibration damping properties of materials – Poisson's ratio

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

Performed at: Laboratory, DASM Institute of Applied Acoustics.

1. Objectives and test objects

– 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.

– Object:

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

2. Experimental procedure

The experimental procedure uses an impedance tube.

Steps to perform:

• Prepare all necessary equipment and measurement samples.
• Perform sample measurement.
• Process and report results.

3. Notes

Measurement samples include 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.
• Measure the shear damping properties of non-self-supporting damping materials.

Role – Importance of Material vibration energy dissipation properties determination testing method – Poisson's ratio

Material vibration energy dissipation properties determination testing method – Poisson's ratio performed by DASM Institute helps meet various practical needs such as:

• Customers wishing to control vibration and noise.
• Businesses needing quality control during production, optimizing the research and development of damping materials.
