Shape derivatives in bi-material level-set optimization with a precise interface: a comparative study
Majd Kosta, Oded Amir
In this study, we investigate and compare formulations for computing shape derivatives in bi-material level-set optimization with precise modeling of the interface. The level-set f…
Maximizing the electromomentum coupling in piezoelectric laminates
Majd Kosta, Alan Muhafra, René Pernas Salomón +2
Asymmetric piezoelectric composites exhibit coupling between their macroscopic linear momentum and electric field, a coupling that does not appear at the microscopic scale. This el…
Level-set topology optimization considering nonlinear thermoelasticity
Hayoung Chung, Oded Amir, H. Alicia Kim
At elevated temperature environments, elastic structures experience a change of the stress-free state of the body that can strongly influence the optimal topology of the structure.…
Mixed projection- and density-based topology optimization with applications to structural assemblies
Nicolò Pollini, Oded Amir
In this paper we present a mixed projection- and density-based topology optimization approach. The aim is to combine the benefits of both parametrizations: the explicit geometric r…
Stress-constrained continuum topology optimization: a new approach based on elasto-plasticity
Oded Amir
A new approach for generating stress-constrained topological designs in continua is presented. The main novelty is in the use of elasto-plastic modeling and in optimizing the desig…
