Abstract

Topology optimization is a design technique that evaluates and determines the optimal material distribution, within a domain, given an objective function and constraint. For the flat, round mirror in this report, the objective function is to obtain maximum stiffness while minimizing the mass. An optimized open-back Beryllium mirror will be evaluated for mass and structural properties. These results will be used to influence a topology optimization study of a closed-back (sandwich) mirror made from an Aluminum, Silicon, and Magnesium alloy, AlSi10Mg, with similar properties to Aluminum 6061. The AlSi10Mg alloy used for this study was chosen for the combination of mechanical properties and usage in additive manufacturing.
