Advanced fuzzy arithmetic for material characterization of composites using guided ultrasonic waves

Leonardo Araque et al.

Summary: In this study, a technique based on guided ultrasonic waves combined with fuzzy arithmetic is developed to quantify the nominal values of inherent epistemic uncertainty in material constants of fiber-reinforced composites. The identified material parameters are defuzzyfied to determine a new set of nominal values for material properties, which may contribute to the development of more efficient nondestructive material characterization techniques in the future.

On the Identification of Orthotropic Elastic Stiffness Using 3D Guided Wavefield Data

Adil Han Orta et al.

Summary: This study investigates the effect of using the in-plane and out-of-plane components of the recorded vibration velocity in the inverse determination of stiffness parameters in scanning laser Doppler vibrometry. The results show that accounting for the in-plane component leads to a more accurate and robust determination of the stiffness parameters.

Lamb wave mode decomposition and reconstruction based on the viscoelastic propagation model

Xuwei Cao et al.

Summary: In this article, a technique based on the viscoelastic propagation model of Lamb waves is proposed to extract the desired mode component, overcoming the challenges of dispersion, multimodal, and attenuative characteristics in viscoelastic media. The technique estimates the parameters of the viscoelastic propagation model and enables the decomposition and reconstruction of the desired mode from spatial-temporal measurement data effectively. Experimental results verify the effectiveness of the technique, showing good performance in noisy circumstances with small reconstruction errors.

Experimental methodology to assess the dynamic equivalent stiffness properties of elliptical orthotropic plates

Fabien Marchetti et al.

Summary: This paper deals with the dynamic characterisation of plate structures with elliptical orthotropic stiffness properties, using an equivalent thin plate theory and a wave fitting approach. The method involves projecting the experimentally determined transverse displacement field of a plate onto an analytical Green's function of an elliptical orthotropic plate based on Hankel's functions, minimizing the error between the projected and measured fields to determine frequency dependent dynamic material properties, validating the fitting approach, and comparing identified flexural rigidities with estimations obtained by analytical models and the IWC method. Consistent results between methods and models are observed for the elliptical orthotropic assumption over a large frequency range (from 1 to 50 kHz).

Robust and baseline-free full-field defect detection in complex composite parts through weighted broadband energy mapping of mode-removed guided waves

Joost Segers et al.

Summary: The study investigated a non-destructive testing approach using broadband piezoelectric excitation and scanning laser Doppler vibrometer measurements to detect damages in fiber reinforced polymers. A mode-removed broadband weighted root mean square (WRMS) energy map was calculated to show high sensitivity to abnormalities in the wave field, without the need for a priori information. The method proved effective for detecting various kinds of damages, including small ones deep inside the material, and could be applied on complex composite parts.

Summary: Model-based approaches using guided waves for damage detection have great potential, but accurate representation of wave propagation behavior is crucial to avoid errors caused by improper assumptions of elastic material properties. Experimental measurements and optimization techniques are used to estimate elastic constants for improved accuracy.
