ASTM E-756 Testing, Measurement, and Support
ASTM E-756 is a test method that determines the vibration-damping properties of materials. It adequately characterizes viscoelastic materials’ mechanical properties, including the loss factor (η), Young’s modulus (E), or the shear modulus (G). This vibrating beam technique measures the dynamic material properties of viscoelastic materials from measurements made on homogeneous beams as well as composite beams.
The American Standards for Testing of Materials adopted this procedure as the preferred method of determining the damping properties of materials. DTI offers testing services per ASTM E-756 to customers, delivering properties used for their internal quality control validation, as well as for design purposes.
DTI retrieves quality data during these procedures that aids in selecting the most suitable materials to control noise and vibration. With an accurate frequency range of 50 to 5000 Hz and temperature variations, this method accurately tests materials used to address structural vibration and noise control. ASTM E-756 encompasses many materials, including metals, enamels, ceramics, rubbers, plastics, reinforced epoxy matrices, and wood.
Customers can use the data to assess structural integrity, damping performance, noise and vibration concerns, and high cycle fatigue issues with a high degree of accuracy.
