Abstract
A novel hybrid-Trefftz finite element (HTFE) for the analysis of symmetric laminated composite plates has been developed. Unlike the existing HTFE formulations, the derivation of this HTFE does not require the particular solutions of simultaneous governing partial differential equations. The Trefftz functions are constructed from the exact solutions of the homogeneous simultaneous governing partial differential equations in a straight forward manner without transforming them into a single governing equation. The HTFE is validated with the authenticated exact solutions. It is observed that this HTFE is an efficient finite element for analyzing laminated composite structures.
