- Abstract
Purpose: The lap joint adhesive layer effects of two laminated circular-cylindrical shells on free vibration analysis are investigated. Modal analysis is studied based on the first order shear deformation shell theory (FSDT) considering compatibility conditions under various boundary conditions. These two laminated cylindrical shells are joined by an adhesive layer, in which type and thickness of the resin as well as length of overlap are very important. Methods: The equation of lap joint of the shell to shell was obtained using Hamilton's principle. The analysis results have been presented for carbon/epoxy, glass/epoxy and aramid/epoxy laminated composite materials. The epoxy, ICPO 9923 and AV 138 adhesive materials are used as the adhesive layer. The generalized differential quadrature method (GDQM) is used for solving the equations. Results: The effects of layups, materials of adhesive and laminated composite cylinders, length ratio, overlap ratio, ratio of thickness of adhesive layer to thickness of shell, various boundary conditions and circumferential wave number on the natural frequency of laminated circular cylindrical lap joint were studied. Furthermore, the comparison between the analysis of free vibration of the present study and the previous research shows a good agreement. Conclusions: The result of this study illustrates that with increasing the overlap ratio, the dimensionless frequency increases. Also, as the adhesive thickness layer raises, the dimensionless frequencies are slightly decreased.
