1. Introduction
ATCP Physical Engineering equipment and products have been projected and manufactured
to provide a long-lasting and top-rated performance. This Installation and Operation Manual
contains all necessary information regarding the use and maintenance of SX-PD Support.
Carefully read this manual before using the support. Improper use may
damage the product and affect its performance.
2. Definitions
Impulse Excitation Technique: The Impulse Excitation Technique is a non-destructive
technique to determine the elastic moduli and damping of materials by the resonance
frequencies of test specimens. ASTM E1876 is the main standard related to the Impulse
Excitation Technique.
Resonance frequencies: Specimen natural frequencies of vibration.
Elastic modulus: Elastic modulus or Young’s modulus is defined as the slope of the stress-
strain curve at the elastic region, as described by Hooke’s Law. The elastic modulus
determined by Impulse Excitation Technique is also termed as dynamic elastic modulus.
Damping: Damping is the phenomenon by which mechanical energy is dissipated in dynamic
systems. It is directly linked to the presence of defects and to the material microstructure.
3. Application and features
SX-PD Support is an apparatus to support specimens for non-destructive characterization of
Young’s modulus and damping of materials by the Impulse Excitation Technique, in
agreement with ASTM E1876 and correlated standards. SX-PD Support was developed to be
used alongside Sonelastic®Systems.
SX-PD Support allows discs and ring-shaped specimens to rest on the nodal lines of the planar
vibration mode. This support is a practical and adjustable system according to the specimen
under test dimensions.
For greater convenience, SX-PD Support may be combined with IED Automatic Impulse
Device.

7. Specimens
7.1 Recommended aspect ratios
Minimum aspect ratios must be observed to avoid coupling between specimen’s vibration
modes. In addition, aspect ratio determines the pattern of frequency spectrum of the acoustic
response. We advise users to standardize the aspect ratio in order to facilitate the frequencies
identification. The table below presents the recommended aspect ratio and typical dimensions
for discs and rings.
Geometry
Recommended aspect ratio
Discs
𝐷𝑜
𝑇≥10
The ration between diameter (Do) and thickness (T) must
be greater than or equal to 10.
Rings
𝐷𝑜
𝑇≥10
The ratio between outer diameter (Do) and thickness (T)
must be greater than or equal to 10.
𝐷𝑜
𝐷𝑖
≥ 2
The ratio between outer diameter (Do) and inner diameter
(Di) must be greater than or equal to 2.

Important observations for preparing and finishing the specimens:
- The recommended dimension tolerance is 2%;
- Faces should be flat and parallel;
- Corners should not be rounded.
Note: Minimum dimensions may vary as a function of aspect ratio and material Young’s
modulus; the frequency should be lower than CA-DP Acoustic Sensor maximum frequency
(96 kHz). It is possible to estimate the frequency using SonelasticSoftware simulation tool.
The higher the Youngs’ modulus, the higher the frequency.
7.2 Placing the specimen
The specimen should be symmetrically placed on the support-cables, and only by its edges.
Typical placement for an abrasive grinding wheel.
