These books cover current research area uncertainty analysis. The different technique is available with this book. The proposed technique is Monte Carlo method, for three hollow composite (Rectangular, Circular And Aerofoil) beams made of laminated composites and subjected to bending loads, has been carried out under uncertainty in bending stress for statical and transient analysis. Bending stress was objective function. Geometric parameters, Material parameters Composite Parameters and Load parameter are randomly varied for optimization within effective range and their effect on bending...
