There are two trends that are motivating research in computational design optimization. First, advances in manufacturing technology such as additive manufacturing (3D printing) have enlarged the design space and engineers need better computation tools to take full advantage of the manufacturing possibilities. Secondly, available computing power is such that thousands of finite element simulations can be performed in hours, better computation tools are required to take advantage of this computing power. The goal of computational design optimization is for the engineer to provide high level objectives (maximize stiffness, reduce cost) and constraints (mass, stress) the computer determines the optimal design by automatically performing thousands of finite element simulations. This talk will provide an overview of gradient-based density methods for topological optimization, with discussions on multiscale design and design under uncertainty.
