Sonelastic® Systems
For Impulse Excitation Technique application, all Sonelastic® Systems include at least a specimen support, an impulse device, an acoustic sensor and the Sonelastic® Software. Below are shown typical systems for small-, medium- and large-sized specimens, which can be customized and automated with accessories.

Sample Supports
he 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.
-
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.

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.
Applications
Sonelastic® Systems are able to test any material with elastic modulus ranging from 0.5 to 1,000 GPa. It non-destructively and simultaneously characterizes the Young’s modulus, Shear modulus, Poisson´s ratio and Damping ratio of ceramics, concretes, composites, biomaterials and metals.

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.
