Probabilistic Design of optimized composite Box Beam by Ansys

This study represents simulation of optimized Rectangular composite beam by using Monte Carlo method. It has been carried out and uncertainty in Maximum bending stress and Deflection is analyzed. Maximum bending stress and Deflection was objective function. Chord length , beam length ,elastic modulus and shear modulusin XY,YZ,XZ of epoxy graphite, ply angle and ply thickness of rectangular section, force are varied within effective range and their effect on Maximum bending stress and Deflection has been analyzed. Ultimately, best set of probabilistic design variable is proposed to reduce Maximum bending stress and Deflection under static loading condition.
