Frequently Asked Questions
Impulse Excitation Technique
Can you give me more information about the impulse excitation technique (IET)?
How do you perform impulse excitation measurements?
How do you perform high temperature impulse excitation measurements?
Which sample geometries can be used to calculate the elastic properties of a material?
Are there any sample size requirements for IET measurements?
Below you can find a reference document, which gives some guidelines to prepare a sample, which can be measured using the impulse excitation technique (IET) at room temperature and at elevated temperatures. In general, rectangular bars are preferred.
If these sample dimensions are not feasible for your applications, contact us to discuss other opportunities!
What is the accuracy and uncertainty of impulse excitation measurements?
Do the samples need to be isotropic and homogeneous?
What are the differences between static and dynamic test methods?
Can we only obtain information about the elastic properties of the material?
Can you send me some publications regarding the impulse excitation technique?
What are the differences between the RFDA room temperature systems?
Below you can find a table to compare the specifications between the RFDA basic and RFDA professional systems.
If you still have questions regarding the RFDA room temperature systems, do not hesitate to contact us!
What are the differences between the RFDA high temperature (HT) systems?
Below you can find a table to compare the specifications of the different RFDA high temperature systems.
If you still have questions regarding the RFDA high temperature systems, do not hesitate to contact us!
Do you offer a measurement service?
After the samples are received at IMCE, they will be analyzed with a short turnaround time and the results will be presented in a clear measurement report.
