Layerwise Finite Element for Thermal Stability Analysis of Laminated Composite Plates
Slojeviti konačni element za analizu termičke stabilnosti laminatnih kompozitnim ploča
Апстракт
In this paper thermal stability of laminated composite plates is analyzed using layerwise finite element. The weak form of the plate mathematical model is derived using layerwise displacement field of Reddy [1], nonlinear strain-displacement relations (in von Karman sense) and linear orthotropic thermo-mechanical material properties. The weak form is discretized using isoparametric finite element formulation. The nine-node Lagrangian isoparametric element is used to derive element stiffness and geometric stiffness matrix. The originally coded MATLAB program is used to analyze the effects of different boundary conditions on thermo-elastic stability of laminate composite plate. The accuracy of the numerical model is verified by comparison with the available results from the literature.
