Abstract
This paper presents a dynamic characterization of the delaminated composite plate structure. The governing Equation of the delaminated composite plate developed using finite element method (FEM) formulation grounded on a classical laminated plate theory. The FEM formulation designed for the delaminated composite plate under bending validated by comparing the natural frequencies evaluated using the present FEM formulation through MATLAB coding and experimental results. Various parametric studies have investigated. Simulation study conducted for different interfaces with different delamination location problems solved by the FEM. It shows that percentage of natural frequency decrease in the delaminated composite plate when compared to the intact composite plate. The significant variation in the natural frequency depends on the delamination location and delamination interface. This study is useful for the designers to tailor the structures with various interface delamination present in the arrangements. Artificial neural network algorithm implemented to study the effect of delamination in laminated composite plate structures
