Topology Optimization of Graded Truss Lattices Based on On-the-Fly Homogenization
Bastian Telgen, Ole Sigmund, Dennis M. Kochmann
We introduce a computational framework for the topology optimization of cellular structures with spatially varying architecture, which is applied to functionally graded truss latti…
Buckling and yield strength estimation of architected materials under arbitrary loads
Morten N. Andersen, Yiqiang Wang, Fengwen Wang +1
Buckling strength estimation of architected materials has mainly been restricted to load cases oriented along symmetry axes. However, realistic load scenarios normally exhibit more…
De-homogenization using Convolutional Neural Networks
Martin O. Elingaard, Niels Aage, J. Andreas Bærentzen +1
This paper presents a deep learning-based de-homogenization method for structural compliance minimization. By using a convolutional neural network to parameterize the mapping from…
Ultra-coherent nanomechanical resonators based on inverse design
Dennis Høj, Fengwen Wang, Wenjun Gao +3
Engineered micro- and nanomechanical resonators with ultra-low dissipation constitute the ideal systems for applications ranging from high-precision sensing such as magnetic resona…
Revisiting the optimal shape of cooling fins: A one-dimensional analytical study using optimality criteria
Joe Alexandersen, Ole Sigmund
This paper revisits the optimal shape problem of a single cooling fin using a one-dimensional heat conduction equation with convection boundary conditions. Firstly, in contrast to…
Topology Optimization with linearized buckling criteria in 250 lines of Matlab
Federico Ferrari, Ole Sigmund, James K. Guest
We present a 250 line Matlab code for topology optimization for linearized buckling criteria. The code is conceived to handle stiffness, volume and Buckling Load Factors (BLFs) eit…
