Sample Supports

The function of the supports on the Impulse Excitation Technique and Sonelastic® Systems is to prop the specimen under its nodal lines while allowing the free vibration. In order to ensure the greatest possible flexibility of geometries, dimensions and modes of vibration ATCP provides a wide range of support options.
If our standard supports fail to meet your requirements, the highly qualified ATCP team will develop a custom model to meet your needs.

Devices por impulse excitation

The impulse device function in the Impulse Excitation Technique is to excite the specimen with a mechanical impulse without emitting sounds or noises within the measurement frequency range. Sonelastic® Systems have several impulse devices options that meet this requirement for small and medium-size specimens in the various geometries compatible with the supports. Besides manual models, there are automatic options that simplify the excitation and allow measurement automation in dependence of time.

Manual Impulse Device for the Impulse Excitation Technique
Automatic Device IED for the Impulse Excitation Technique

Acoustic sensors

The sensor function in the Impulse Excitation Technique is to capture the specimen acoustic response to impulse excitation with the high immunity to ambient noise. Sonelastic® Systems have directional sensors options for 70 Hz - 96 kHz frequency range that meet this requirement. Sonelastic® Systems also have modules and cards for signals acquisition and digitization, and accessories for holding the acoustic sensors.

Acoustic Sensor Microphone CA-DP for the Impulse Excitation Technique
Acoustic Sensor Base for the Impulse Excitation Technique
Acoustic Sensor CA-DP-USB-ADAC for the Impulse Excitation Technique
Acoustic Sensor CA-DP Tripod for the Impulse Excitation Technique

Sonelastic® Software

Sonelastic® Software main functions in the Impulse Excitation Technique are to analyze the specimen acoustic response, detect the frequencies and calculate the elastic moduli and damping. Additionally, Sonelastic® Software is able to calculate the speed of P-waves and S-waves, estimate frequencies and perform automatic measurements in dependence of time.

  • Improving Finite Element Analysis (FEA)

    The knowledge of the elastic moduli exact values is crucial for accurate finite element analysis and reliable modeling. Sonelastic® Systems enables you to measure the Young’s modulus, the Shear modulus, the Poisson´s ratio and damping of any rigid material. It is also possible to measure the main elastic coefficients of composites and others anisotropic materials.

What customers have to say about ATCP

  • Prof. Dr. RODRIGUES, J. A.(GEMM/DEMA/UFSCar)REFRACTORIESATCP has a good technological base and scientific knowledge compatible with the area it operates. The Sonelastic products have quality and good performance, besides the attractive prices when compared to equivalents. The company’s director is always willing to discuss clients’ specific needs.
  • Prof. Dr. Alexandre L. S. Borges(ICT/SJC-UNESP)BIOMATERIALSSonelastic is frequently used by our post-graduation students and researchers. Determining properties is something which can be easily done; however, because we use highly stiff materials, the specimen’s dimensions need to be big and this makes the research a bit more expensive. For the characterization of polymers used for restorations and cementation, Sonelastic is sensational because small dimensions (20x7x2mm) can give us both Young’s modulus and Poisson’s ration. The equipment is easy to use and a short 30-minute training is enough to allow post-grad students to use it independently.
  • Prof. Dr. Salomão, R.(Mat. Eng. Depart./EESC-USP)REFRACTORIESIn my research group, we use Sonelastic to measure elastic modulus of porous ceramic structures used as thermal insulators. The equipment is very easy to use, and maintain, and it is accurate (in comparison to destructive techniques). The technical support provided by ATCP is certainly one of the best I have experienced. Besides, as a Materials Science teacher, I often use Sonelastic as a didactic aid to explain mechanical properties of materials, effects of thermal treatments and thermal shocks, and non-destructive tests.
