Vibration Analysis of Cracked Composite Laminated Plate: A Review

Abstract

Composites are one of the rapidly consuming materials due to their utmost attractive applications ranging from the aerospace to the agricultural products. The composite structures usually experience vibration during service. Experiments showed that presence of delamination in composite structures is one of the major causes of failures in laminated structures. Presence of delamination in a structure not only significantly impacts the stiffness of the structure with declining trends but also affect their vibration properties. The purpose of this paper is to review the literature studies on the effect of vibration on composite delaminated structures subjected to different boundary conditions. The literature studies have been classified on the basis of methodology adapted to analyze the problem i.e experimental work, analytical approaches and finite element methods. In this review particular attention has been given to the study of results attained from the analytical analysis, finite element and experimental works. Comparison of the results conducted by other researchers in the field of the free and forced vibration behavior of the composite laminates subjected to delamination or cracked structures has also been studied. Studies have shown that the location and size of delamination in composite structures significantly impacted the natural frequencies and mode shapes.

Investigating the Effect of Delamination Size, Stacking Sequences and Boundary Conditions on The Vibration Properties of Carbon Fiber Reinforced Polymer Composite

“…On the comparison of results for higher modes [7][8][9][10][11][12] , Mode 7 has the lowest percentage error as compared to mode 12 in 0/90/45/90 stacking sequences as shown in Table 2. On contrary to 0/90/45/90, 0/45 and 0/90 sequences showed an increase in percentage error on an increase in modes.…”

“…The applications of carbon-fiber reinforced polymer composite structures have largely increased due to high strength carbon fibers 6 . Cracks or delamination in the laminate of composite structures are unavoidable during the service life of a composite structures 7 . There can be other parameters that also affect the performance of the composites.…”

“…There can be other parameters that also affect the performance of the composites. Moreover cracks in the structure leads to propagation that ultimately leads to the failure of the composite laminate 8 . In composite structure, it has been validated experimentally that presence of crack or delamination affects the performance of the structure due to huge displacements or deformations 9 .…”

Composite Automobile Fender Impact Testing with a Spherical Ball

“…An investigation with dedicated software applications ABAQUS and Matlab has been performed in order to capture the influence of the delamination size, lamina sequence and boundary conditions on the vibrations behavior of composite structures [12]. Also, with ABAQUS/Explicit module, a strategy has been presented for the finite element analysis of laminates subjected to impact and their postimpact compression parameters [13].…”

Experimental, Numerical and Finite Element Vibration Analysis of Delaminated Composite Plate

“…It must not be forgotten that the carbon-fiber layout also has the ability to influence the carbon-fiberreinforced polymers properties. Composite laminates are preferred due to their many advantages such as their high-strength, bending stiffness and resistant to expansion [5][6][7][8][9][10]. Usually, composite laminates are formed from a hybrid of fiber-matrix layers.…”
