On Manufacturing Method Decision
With the numerous applications we have reviewed to this day, I have seen that topology optimization is usually applied after the manufacturing method is decided. I wonder about the efficiency of such an exercise. If the aim is obtaining the … Continue reading

GENERATING CAD PARAMETRIC FEATURES
The thesis by William Robert Blattman (link) studies generation of a parametric CAD model from topology optimization results. As I stated in many of my previous articles, interpretation of topology optimization is the weakest link in the design cycle at … Continue reading

Bridge Optimization
In this nice presentation (link) topology optimization of bridges is elaborated. .
THIN-SHELL BRIDGE STRUCTURE
Topology optimization of a thin shell bridge was done (link) and compared to a real bridge. The original bridge is Knokke bridge located in Belgium which did cost $1,700,000 euro to build (link2). The optimized bridge has better mechanical properties … Continue reading
Topology Synthesis of Structures Using Parameter Relaxation and Geometric Refinement
In this technical publication (link) by Marshall Space Flight Center of NASA, topology optimization for compliant mechanisms is studied. Genetic Algorithm based optimization is used, also featuring subdivision to smooth the geometry, also geometry relaxation, so that the mesh is … Continue reading

Multiresolution Topology Optimization (MTOP)
Tam H. Nguyen et al. developed this novel method called Multiresolution Topology Optimization (MTOP) (link), which utilizes different meshes, namely the displacement mesh , the design variable mesh and the density mesh. Using a coarse displacement mesh which is used … Continue reading
Topology-free optimization – an application to turbine internal cooling geometries
This work is more related to CFD optimization which can change the topology of the structure, than topology optimization (link). Hence the name is topology-free optimization, to denote that it can change the topology. An integrated approach is followed where … Continue reading
DIE CAST AUTOMOTIVE BACKREST FRAME
Actually I thought a lot about whether I should post this or not. When I found this thesis (link), I was very excited. I know that magnesium backrest frames are used in some high-end cars, and further lightening can be … Continue reading
