Papers
Below are key publications demonstrating the use of impulse excitation for determining elastic properties such as Young’s modulus, shear modulus, and Poisson’s ratio:
The innovative impulse excitation technique for high-temperature mechanical spectroscopy
Recent developments in digital signal analysis have allowed substantial progress in the field of impulse excitation techniques (IET), i.e. the mechanical–spectroscopic analysis of ‘impulse excited’ resonant vibrations. The new IET-devices determine several impulse excited resonance frequencies simultaneously.
Glass microstructure evaluations using high temperature mechanical spectroscopy measurements
This paper compares the microstructures of several glasses by measuring the Young’s modulus and internal friction as a function of temperature, using the impulse excitation technique (IET).
High temperature properties of ZnO ceramics studied by the impulse excitation technique
This study reports on impulse excitation technique (IET) measurements up to 900 °C in air performed on various grades of ZnO ceramics, containing bismuth and antimony oxides as dopants. The IET provides dynamic elastic (E-modulus) and damping properties as a function of temperature.
Microstructure research of glasses by impulse excitation technique (IET)
The stiffness and internal friction (Q−1) of a CaO–Al2O3 SiO2 glass and an Na2O–CaO–SiO2 glass have been measured from room temperature to their respective glass transition temperatures (Tg) using the impulse excitation technique (IET).
💡 These works form the foundation of modern impulse excitation methods and the validation of GrindoSonic instruments.
