Course Objectives and Outcomes

Catalog description: Structural optimization via surrogate modeling. Application of techniques of numerical optimization to design of truss, frames, and composite laminates. Calculation of sensitivity of structural response. Approximation and fast reanalysis techniques. Optimality criteria methods.

The objective of the course is to learn the fundamentals of engineering optimization with emphasis on the application of surrogate models, optimality criteria, and discrete and continuum design sensitivity as well as providing hands on experience using commercial optimization software to formulate and solve design optimization problems of relevance to mechanical and aerospace engineers. The outline of the course is as follows:

• Introduction to surrogate modeling
• Polynomial response surfaces
• Design of experiments
• Advanced surrogate models, including neural network, radial basis model, and Kriging
• Optimization definition and formulation
• Numerical optimization algorithms
• Global search optimization algorithms
• Topology optimization
• Design parameterizatio
• Design sensitivity analysis
