• Design concentrated solar power truss structure that handles the trough (mirror) under the forces exert by the wind and the structure weight using FEA and CFD techniques. A full FEA was performed on the truss structure using Femap NX Nastran software• Performing a stochastic analysis for composite plates using reliability analysis, Monte Carlo simulation, neural-network techniques and finite element method• Reduced the probability of failure computational time by 20% by using neural network-based reliability method. • Optimized the natural frequency of a laminated composite plate with geometrical and material properties uncertainties using a home-made FEA MATLAB code• Minimized the composite plate weight while keeping the plate probability of failure under 0.001. This was achieved by applying risk analysis and design optimization techniques
