3D architected isotropic materials with tunable stiffness and buckling strength
Fengwen Wang, Ole Sigmund
This paper presents a class of 3D single-scale isotropic materials with tunable stiffness and buckling strength obtained via topology optimization and subsequent shape optimization…
On the competition for ultimately stiff and strong architected materials
Morten N. Andersen, Fengwen Wang, Ole Sigmund
Advances in manufacturing techniques may now realize virtually any imaginable microstructures, paving the way for architected materials with properties beyond those found in nature…
Internal contact modeling for finite strain topology optimization
Gore Lukas Bluhm, Ole Sigmund, Konstantinos Poulios
The present work proposes an extension of the third medium contact method for solving structural topology optimization problems that involve and exploit self-contact. A new regular…
Compact 200 line MATLAB code for inverse design in photonics by topology optimization: tutorial
Rasmus E. Christiansen, Ole Sigmund
We provide a compact 200 line MATLAB code demonstrating how topology optimization (TopOpt) as an inverse design tool may be used in photonics, targeting the design of two-dimension…
Inverse design in photonics by topology optimization: tutorial
Rasmus E. Christiansen, Ole Sigmund
Topology optimization methods for inverse design of nano-photonic systems have recently become extremely popular and are presented in various forms and under various names. Approac…
Topology Optimization and 3D printing of Large Deformation Compliant Mechanisms for Straining Biological Tissues
P. Kumar, C. Schmidleithner, N. B. Larsen +1
This paper presents a synthesis approach in a density-based topology optimization setting to design large deformation compliant mechanisms for inducing desired strains in biologica…
Topology Optimization of Two Fluid Heat Exchangers
Lukas Christan Høghøj, Daniel Ruberg Nørhave, Joe Alexandersen +2
A method for density-based topology optimization of heat exchangers with two fluids is proposed. The goal of the optimization process is to maximize the heat transfer from one flui…
Large scale three-dimensional manufacturing tolerant stress-constrained topology optimization
Gustavo Assis da Silva, Niels Aage, André Teófilo Beck +1
In topology optimization, the treatment of stress constraints for very large scale problems has so far not been tractable due to the failure of robust agglomeration methods, i.e. t…
A new generation 99 line Matlab code for compliance Topology Optimization and its extension to 3D
Federico Ferrari, Ole Sigmund
Compact and efficient Matlab implementations of compliance Topology Optimization (TO) for 2D and 3D continua are given, consisting of 99 and 125 lines respectively. On discretizati…
