RFDA Essential

Identify elastic properties with precision:

The RFDA Essential material testing equipment enables you to identify elastic properties at ambient temperature. With the RFDA Essential’s advanced capabilities, you can effortlessly determine Young’s modulus (E), Shear modulus (G), as well as Poisson’s ratio (ν) in a single measurement, saving you time and effort.

Non-Destructive:

Experience the advantages of non-destructive testing with the RFDA Essential. By measuring near the origin of the stress/strain curve, you can obtain dynamic material properties without compromising the integrity of your samples which in turn preserves your valuable materials while obtaining accurate results.

High accuracy:

The RFDA algorithm utilizes an iterative process that analyzes the sample’s natural frequencies with high accuracy. The resulting frequency data, combined with the damping value (Q^-1), provides you with a comprehensive understanding of your material’s behavior.

Wide range of applications:

From material science to quality control and beyond, the RFDA Essential finds its place in diverse industries. Whether you’re conducting research, ensuring product quality, or optimizing manufacturing processes, the versatility of the RFDA Essential covers a wide range of applications.

Ease of use:

The RFDA Essential comes equipped with a universal sample support system as well as an excitation device (manual and semi-automatic), microphone, and the powerful RFDA System 20. The user-friendly interface and intuitive controls make operation easy which allows you to focus on your analysis.

Built on expertise:

IMCE measurement systems are build on innovative technology developed by our in-house R&D. The RFDA Essential is designed with more than 30 years of experience, innovation and commitment to excellence ensuring a measurement system of the highest standard.

Optional software toolkit designed to study the amplitude dependent behavior of materials, which can be used to detect defects in materials at an early stage.

To perform a non-linear analysis, the measured signal is divided in different parts (time or amplitude window). In each window, the frequency and damping parameters are determined and plotted as function of the vibration amplitude. A shift of these parameters vs. the amplitude is characteristic for non-linear behavior and can give useful information regarding the formation of micro cracks. In general, a certain amplitude threshold is required to open/close the defects (for example: micro cracks as well as dislocations, …) which leads to non-linear behavior.

Including following functions:

• Step analysis of the time signal.
  The user can define the segments in a time or amplitude window.
  This analysis can be performed during the measurement or on a batch of earlier saved signals.
• When the amplitude of the vibration (for example: signals from laser-vibrometer) and the
  dimensions and shape of the sample are known, it is possible to calculate the maximum
  deformation amplitude in the signal.
• Full integration in the RFDA Essential software

This optional toolkit offers a simplified user interface with go/no go Indication for use in production environments.
All measurement set-up and tolerances are product type configurable.

Within the software’s lab environment, a comprehensive analysis of a particular product can be conducted. This analysis results in a product type that includes the essential parameters for making a go/no-go decision. In production environments, these parameters ( available in read-only mode) can be loaded to inspect the relevant product type.

The user’s task is straightforward: position the sample on the support as indicated by the software, execute the measurement, and let the Product Inspection Toolkit compare the obtained values against the predetermined tolerances within the product type. Following the comparison, the software promptly signals a Go/No-Go/Suspect status.

Including following functions:

• Managing of product types and setting of tolerances
• Password protection of user levels
• Save/Load of product types
• Visual representation of sample setup
• Go/No-Go/Suspect indication
• Batch measurements

This module is fully integrated in the RFDA Essential software.
