Abstract

This paper evaluates numerically the dynamic behavior of structural composite laminate materials in relation to the angular change in fiber layers of the laminated composite. The behavior of the material is modeled through finite element method, where the First Order Shear Deformation Theory (FSDT) is used which is implemented on a rectangular element serendipity containing eight nodes. The mathematical modeling has been implemented using the commercial available software MATLAB®. Through numerical simulations, it will be possible to obtain the natural frequencies. And we will present a sensitivity analysis with respect to the fiber orientation parameter.
 
Key words: Dynamic behavior, composite laminated plates, First Order Shear Deformation Theory (FSDT), fiber orientation parameter.
