Abstract

This paper presents the vibration analysis of orthotropic laminated composite plate using finite element method. A suitable finite element model is proposed and developed based on first order shear deformation theory using ANSYS parametric design language (APDL) code. The model has been discretized using an appropriate eight nodded element (SHELL 281) from the ANSYS element library. The free vibrations are computed using Block-Lanczos algorithm, initially the model response is verified for orthotropic plate with the available literature. The convergence study has been done for the developed model. A number of examples concerning various thickness-to-span ratios, material properties and boundary conditions are considered. The boundary conditions of the plate play an important role in the free vibrations of the plate. The author proved that non-dimensional frequencies are higher for fully clamped boundary condition in comparison to other boundary conditions.
