MATLAB codePiezoelectric actuatorPiezoelectric energy harvesterIn this paper, two separate topology optimization MATLAB codes are proposed for a piezoelectric plate in actuation and energy harvesting. The codes are written for one layer piezoelectric plate based on 2D finite element modeling. As such, ...
The code can also be executed without the MATLAB Image Processing Toolbox, but the behaviour may change, which is discussed in Sect. 2. References Aage N, Nobel-Jørgensen M, Andreasen CS, Sigmund O (2013) Interactive topology optimization on hand-held devices. Struct Multidisc Optim 47:1–...

MATLAB code isintended for educational purposes to help those new tothe field of structural topology optimization as well asthose who have only used other topology optimizationapproaches before.To the authors’ knowledge, there are a number of freecodes for topologyoptimizationofcontinuum structures,...
The Matlab optimizer will solve the standard topology optimization problem using less iterations at the cost of a slightly increased CPU-time per iteration. http: //www.mekanik.ikp.liu.se/andridiv/matlab/ theory.html. The code was intentionally kept compact in order to keep the total number ...

导读:Sigmund在2001年在Structural and Multidisciplinary Optimization 发表一篇名为《A 99 line topology optimization code written in Matlab》论文。该论文附带一个使用Matlab编写的拓扑优化程序。这个只有99行代码的程序基于Matlab环境构建了一个完整的拓扑优化流程:前处理(构建有限元仿真模型), 有限元模型分析计算,拓扑...
The TOBS is a gradient-based topology optimization method that employs binary design variables and formal mathematical programming. Besides its educational purposes, the 101-line code is provided to show that topology optimization with integer linear programming can be efficiently carried out, contrary ...
