Delamination Evolution of FRP Composite Plate using Modal Analysis

Abstract

This paper presents the damage analysis of a three-dimensional (3D) finite element replica of delaminated E-glass composite plates is developed to study the internal delamination in the FRP composite plates. FEM software ANSYS is used to model and determine the natural frequencies of delaminated composite plates. Natural frequencies as well as modal displacements are intended for a selection of case by means of different size in addition to delamination characteristics. This illustration proves development of the accuracy of results for the delamination in composite plates. The analyses give you an idea with location to that implementation of delamination damage modes and are required for accurate simulation of the three dimensional delamination plates.
