Comparative Study of Several Methods for the Calculation of Ultrasonic Guided Waves in Composites

摘要

The objective of this study is studying the different predictive models for evaluating dispersion curves of ultrasonic guided waves in composites. The paper reviews different algorithms used for wave propagation analysis in layered composite plates: (a) Transfer Matrix (TM), (b) Global Matrix (GM), (c) Semi-Analytical Finite Element method (SAFE), (d) local interaction simulation approach (LISA), and (e) Equivalent Matrix (EM) method applied on cross-ply cases. Description of each technique is covered. Then, advantages and distinct features of those techniques are presented. Case studies for unidirectional, cross ply, and general quasi isotropic laminates are presented. Finally, experimental and finite element simulation studies were performed on glass fiber reinforced polymer composites (GFRP).
