Evaluation of Geometrical Nonlinear Behaviour of FRP Composite Plate Using Finite Element Method

Cheboyina Jeevitha, M. Mounika, P.Phani Prasanthi

Abstract


The work presents the prediction of nonlinear behavior of a square plate made of composite material under uniform transvers pressure using 3-D finite element analysis. Transverse deflection, Normal stresses and Shear stresses are evaluated for different values of load and by varying the number of layers. The effect of loading and variation of stresses in both the analyses for different lay-up of composite laminated plate are determined. The study also includes the effect of the layer thickness for different lay-up responses of laminate under the clamped boundary conditions. The commercial Finite element analysis software ANSYS has been successfully executed for both linear Static analysis and geometric nonlinear static analysis.
