Abstract

Lightweight composite structures have been increasingly used in the aerospace, automotive and marine applications because of good properties such as high stiffness and strength to weight ratio. An in-depth understanding of the vibration behaviour of composite structures with different configurations is of vital importance to achieve optimal structural design with superior dynamic performance. In this paper, vibration analysis of a simply-supported orthotropic laminated composite plate is carried out. Both theoretical and numerical methods are employed to obtain the free vibration behaviour in terms of natural frequencies and mode shapes as well as forced vibration characteristics. The first-order shear deformation laminate theories (FSDT) are used to obtain the equations of motion and the steady-state dynamic response. The analytical results are verified by comparing with those obtained from finite element model. The effects of different structural parameters such as stacking sequence and fibre angles on dynamic behaviour of the laminated composite plate are investigated. The findings provide deeper understanding of the vibration properties of composite laminates for enhanced dynamic designs of such structures
