A quick overview of finite-variable optimization and calculus of variations. Analytical size optimization of bars and beams for stiffness, flexibility, strength, and stability criteria in the framework of variational calculus. Gradient-based computational optimization of trusses, frames, and continuum structures. Sensitivity analysis for parameter, shape, and topology variables. Shape optimization. Topology optimization. Design parameterization for topology optimization of coupled structural problems involving thermal, electro-thermal, electrostatic, fluid, and other multiphysics domains.
After taking this course, the students will be able to:
Formulate structural optimization problems in the framework of calculus of variations as well as finite-variable optimization.
Become familiar with principles of structural optimization and be able to solve them analytically when it is possible and computationally in most cases.
Read and understand the contemporary literature on structural optimization in general and topology optimization in particular.
