Stiffener layout design for thermoelastic spacecraft structures using multi-physics topology optimization

The performance requirements of optical instruments in space telescopes become increasingly demanding. Designing thermoelastic structures is key to account for thermal distortions to achieve the required performance, and modal analysis is required to ensure their survival. This thesis investigates how topology optimization can improve upon...

Simultaneous optimization of the topology and the layout of modular stiffeners on shells and plates

Stiffened shells and plates are widely used in engineering, but their performance is highly influenced by the arrangement, or layout, of stiffeners on the base shell or plate and the geometric features, or topology, of these stiffeners. Moreover, structures with modules are beneficial, since it allows for increased quality control and more...
