The numerical study of the reinforcement layer orientation effect on the behaviour of laminated plates

Abstract

The analysis of the simply supported square laminated plate was conducted employing two distinct Finite Element Method (FEM) models: one representing a quarter-section of a layered laminated composite plate, and the other representing the entire layered laminated composite plate. It was found that the plate's behavior and displacements are significantly influenced by the orientation of the fibers. Moreover, the quarter-section model of the layered laminated composite plate demonstrated limitations in its universal applicability.
