This Young Investigator Awards fellowship will provide focus and innovation for optimization of structures in the offshore industry. The fellowship will enable this to be achieved by providing time and critical mass to build new expertise in multiphysics topology optimization with design-dependent loads. Methods based on explicitly defined boundaries (level set and discrete design variables) will be developed to individually tackle each of the static and dynamic loading conditions imposed by offshore locations, including fluid pressure, current loads, wind loads, subsea soil reaction, thermal expansion and underwater acoustics. The developed methodologies will be further combined in realistic multiple load cases within the offshore structural design scenario. With a four-year base funding, a team of dedicated researchers based in Santos-SP and national and international collaborators, we will deliver computational methods and codes for innovative structural design in offshore engineering.
