Wu, J. (author), Sigmund, Ole (author), Groen, Jeroen P. (author)Multi-scale structures, as found in nature (e.g., bone and bamboo), hold the promise of achieving superior performance while being intrinsically lightweight, robust, and multi-functional. Recent years have seen a rapid development in topology optimization approaches for designing multi-scale structures, but the field actually dates back to...review 2021

Groen, J.P. (author), Wu, J. (author), Sigmund, Ole (author)This paper concerns compliance minimization and projection of coated structures with orthotropic infill material in 2D. The purpose of the work is two-fold. First, we introduce an efficient homogenization-based approach to perform topology optimization of coated structures with orthotropic infill material. The design space is relaxed to allow...journal article 2019

Groen, J.P. (author), Langelaar, Matthijs (author), Sigmund, O (author), Ruess, M. (author)This article presents a detailed study on the potential and limitations of performing higher-order multi-resolution topology optimization with the finite cell method. To circumvent stiffness overestimation in high-contrast topologies, a length-scale is applied on the solution using filter methods. The relations between stiffness...journal article 2017
