A Matlab code for analysis and topology optimization with Third Medium Contact
Andreas Henrik Frederiksen, Ole Sigmund, Federico Ferrari
We present a Matlab code for modelling and topology optimization of hyperelastic structures, including contact modelled by the Third Medium Contact (TMC) approach. By using the so-…
Optimization of the initial post-buckling response of trusses and frames by an asymptotic approach
Federico Ferrari, Ole Sigmund
Asymptotic post-buckling theory is applied to sizing and topology optimization of trusses and frames, exploring its potential and current computational difficulties. We show that a…
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…
Revisiting element removal for density-based structural topology optimization with reintroduction by Heaviside projection
Reza Behrou, Reza Lotfi, Josephine Voigt Carstensen +2
We present a strategy grounded in the element removal idea of Bruns and Tortorelli [1] and aimed at reducing computational cost and circumventing potential numerical instabilities…
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…
Towards solving large scale topology optimization problems with buckling constraints at the cost of linear analyses
Federico Ferrari, Ole Sigmund
This work presents a multilevel approach to large--scale topology optimization accounting for linearized buckling criteria. The method relies on the use of preconditioned iterative…
Revisiting topology optimization with buckling constraints
Federico Ferrari, Ole Sigmund
We review some features of topology optimization with a lower bound on the critical load factor, as computed by linearized buckling analysis. The change of the optimized design, th…
