Multidisciplinary Approach to Optimizing Topology of Parts for Additive Manufacturing
摘要
The chapter presents a multidisciplinary approach to topology optimization of parts produced by additive manufacturing. The approach combines nonlinear optimization techniques with numerical methods in deformable solid body mechanics. A layout problem to generate elliptical perforations considering a corresponding boundary value problem is formulated. Special mathematical modeling tools are used for describing the problem constraints. The maximal mechanical stress in the parts under the load is calculated. A multi-start strategy using a smart feasible point algorithm is applied to solving the layout problem. Numerical examples are presented and compared with benchmark results.
