TL;DR: The convergence behavior of the optimization process is discussed, as well as control over the slope and smoothness of thelevel-set function, hole nucleation and the relation of level-set methods to other topology optimization methods.

TL;DR: An orbital mechanics model based upon finite-element analysis has been developed and it is shown that the supporting action of the orbital fat plays an important role in the suspension of the eye in the orbit and in stabilization of rectus muscle paths.

TL;DR: A unified aggregation and relaxation approach for topology optimization with stress constraints is proposed, which concurrently aggregates the constraints and relaxes the feasible domain, thereby making singular optima accessible.

TL;DR: Sadeghian et al. as discussed by the authors determined to what extent surface effects, such as surface stress, surface elasticity, surface contamination and native oxide layers, influence the effective Young's modulus of silicon nanocantilevers.

TL;DR: A novel topology optimization formulation is presented which concurrently optimizes the structure and the fabrication sequence, and is demonstrated on three fabrication settings, considering self-weight of the intermediate structures, process-dependent critical loads, and time-dependent material properties.
