Optimization of Shape Parameter and Exponent of Generalized Multiquadrics Using Genetic Algorithm for Static Analysis of Laminated Composite Plates

In the present paper, static analysis of laminated composite plates is studied by the meshless global collocation method based on generalized multiquadrics radial basis function. The generalized multiquadric radial basis function has the shape parameter and exponent which have the important effect in the accuracy of the approximation. The genetic algorithm is used to optimize the shape parameter and exponent of generalized multiquadric radial basis function. The deflection and stress of simply laminated composite plates under sinusoidal load are calculated using the generalized multiquadrics with optimal shape parameter and exponent. Present results of deflection and stress are compared with the analytical solutions of other literature which verify the validity and accuracy of present method.
