Proportional Topology Optimization under ‎Reliability-based Constraints [PDF]

Journal of Applied and Computational Mechanics, 2022
Topology optimization is a methodology widely used in the design phase that has gained space in engineering. On the other hand, uncertainty is present in material properties, loads, and boundary conditions in practically any design.
