Optimal Design of Geometrically Nonlinear Structures  Using Topology Optimization

Optimal Design of Geometrically Nonlinear Structures Using Topology Optimization

By Ho Duc Dung
This study deals with the stiffness design of geometrically nonlinear structures using
topology optimization. Bi-directional Evolutionary Structures Optimization (BESO) is
employed to implement the design process. The geometrically nonlinear behavior of the
structures are modeled using a total Lagrangian finite element formulation and the
equilibrium is found using a Newton-Raphson iterative scheme. The topology ...
