Topology optimization is a tool for finding a domain in which material is placed that optimizes a certainobjective function subject to constraints. Here topology optimization is attempted on an interstage structure of a heavylaunch capability launcher being developed by ISRO. Based on static analysis as well as functional requirements,optimization response and constraints were proposed. Topology optimization method based on density approach iscurrently employed for the structure with multiple load cases and multiple constraints. Constraints on uniformity of thereaction force are also considered in this model. Finally, based on the reaction forces, a displacement and stressconstraint, an optimal layout of the structure is presented. The softwares used are the preprocessor HyperMesh,optimization tool OPTISTRUCT and HyperView which are parts of the software suite HyperWorks from AltairEngineering.
