“…The reason is that the correction factors depend the shape of structures are difficult to obtain accurately. Thus some researches have been done about mechanical parameters detection in different materials [27][28][29][30][31][32][33][34][35][36][37], environmental variability [38][39][40][41][42][43][44][45], different dimension sizes [46], etc., based on beams of rectangular cross section and rods of circular cross section only. Moreover, we try to do some exploration about mechanical parameters detection for laminated composites based on plates of rectangular cross section.…”

This study suggests a simple, quick and non-destructive method for investigation of mechanical parameters (dynamic Young's modulus, dynamic shear modulus and Poisson's ratio) detection for rectangular plate structures in laminated composites which only utilizes the fundamental resonant frequency in flexural and torsional modes, mass and dimensions of structures. The method is based on the impulse excitation technique (IET) to pick up the fundamental resonant frequency and then the corresponding formulas are applied to evaluate the mechanical parameters. Numerical simulations using finite element method (FEM) and experimental investigations of several cases based on IET are introduced to verify the accuracy of the IET formulas. The results show that the IET is applicable for mechanical parameters identification for laminated composites plates. The method is expected to detect mechanical parameters of other more complicated structures.

“…The impulse excitation technique (IET) is a well-established mechanical spectroscopic technique analyzing the internal friction and Young's modulus (E) of materials as a function of temperature (16)(17)(18)(19)(20). IET is a resonance method and measures the resonant frequency of a specimen by exciting it mechanically with an impulse tool.…”

The anelastic relaxation process in crystalline solids is influenced by various mechanisms including a.o. diffusion of point defects, dislocation formation, movement and multiplication. To analyze the type and concentration of relaxing units participating in a particular thermally activated process, measuring the temperature dependent internal friction is a well-known approach. In the present study, the impulse excitation technique was used to analyze the internal friction in single crystal Ge in the <111>-, <110>- and <100>- directions between room and melting temperature. The internal friction spectra reveal up to three internal friction peaks. To interpret the observed internal friction peaks, various aspects of the peaks such as activation energy, position and relaxation time will be discussed.
