A new trigonometric zigzag theory for buckling and free vibration analysis of laminated composite and sandwich plates

On the Free Vibration Analysis of Laminated Composite and Sandwich Plates: A Layerwise Finite Element Formulation

“…However, ESL approach fails to capture precisely the local behavior of sandwich structures. This drawback in ESL was circumvented by the Zig-Zag (ZZ) and layerwise (LW) approaches in which the variables are linked to specific layers (Belarbi and Tati 2015, Belarbi et al 2016, Ćetković and Vuksanović 2009, Chakrabarti and Sheikh 2005, Kapuria and Nath 2013, Khalili et al 2014, Khandelwal et al 2013, Marjanović and Vuksanović 2014, Maturi et al 2014, Sahoo and Singh 2014, Singh et al 2011, Thai et al 2016.

Free Vibrations Analysis of Composite Laminate Plates Used in Automotive Industry

“…The differences in results obtained by various shape functions grow with the increase of the relation , which can most clearly be seen in the shape function proposed by Viola at al. Generally, the method which was implemented in Matlab provides good matching with the values presented in the papers of authors dealing with these problems [9], [22], [23], [24]. With thick and moderately thick plates, where a / h <20 there are bigger discrepancies in the values of the dimensionless frequency.…”

Study on shear postbuckling failure of composite sandwich plates by a quasi-conforming finite element method

“…Chen et al [9] simulated the postbuckling behavior of face/core debonded composite sandwich plate. Recently, based on the nonlinear Z-ZT, Sahoo and Singh [10] presented a new inverse hyperbolic zig-zag element, which shows very high accuracy in analyzing the free vibration of thick sandwich plates. Generally, the postbuckling of composite sandwich plates is in connection with various damages.…”
