Reliability-Based Topology Optimization with Analytic Sensitivities
It is a common practice when designing a system to apply safety factors to the critical failure load or event. These safety factors provide a buffer against failure due to the random or un-modeled behavior, which may lead the system to exceed these limits. However these safety factors are not …

Segmental multi-point linearization for topology optimization and reliability analysis
This paper proposes an efficient gradient-based optimization algorithm to solve reliability-based topology optimization (RBTO) of structures under loading and material uncertainties. Topology optimization is a powerful design tool as it can provide the most efficient material layout for structural …

Reliability-based co-design and its applications to wind energy and mobile energy storage systems
… autonomous systems relies on both its physical design and the appropriate control strategies, which often takes place at an early stage of design. The plant design and the control design are strongly coupled. Neglecting this coupling effect may cause an imbalance in the feasible design spaces of …
