# Topology optimization

TO is different from shape optimization and sizing optimization in the sense that the design . It works by taking a solid block of material in any shape and removes material from it to minimize or maximize an optimization objective such as mass, displacement, or compliance while satisfying . The selection of component material and design is an important topic in industry to produce sustainable and competitive products. To fulfil strength and endurance requirements on a component level, topology and shape optimization can be used as design tools in early phases of the design process. The Matlab code presented in this page is intended for engineering education.

Students and newcomers to the field of topology optimization can find the code here and download it. The code may be used in courses in structural optimization where students may be assigned to do extensions such as multiple load-cases, . In the past two years, it has gained popularity because of its availability in computer- aided design (CAD) software that is both easy-to-use and affordable. Also, the optimization is great at creating strong, lightweight parts with less material. Original part (left) compared to a topology – optimized part (right). Image courtesy of Dassault Systèmes.

The topology optimization process carves material away from design spaces, creating the lightest structure capable of withstanding the forces you apply to your model. This approach is ideal for maximizing the stiffness of components while trying to achieve a desired mass target.

It can also be used to . This paper presents an efficient and compact Matlabcode to solve three- dimensional topology optimization problems. The 1lines comprising this code include finite element analysis, sensitivity. By now, the concept is developing in many different directions, including “density”, “level set”, “topological derivative”, “phase field”, “evolutionary” and several others. You can find the best design of a structure with topology optimization.

We explain how, using a bridge example and COMSOL Multiphysics. This paper proposes a new topology optimization metho which can adjust the geometrical complexity of optimal configurations, using the level set method and incorporating a fictitious interface energy derived from the phase field method. First, a topology optimization problem is formulated based on the level set metho . In this context the lay-out of the structure includes information on the topology, shape and sizing of the structure and the material distribution method allows for addressing all three problems simultaneously. Sizing, shape, and topology optimization problems address different aspects of the structural design problem.

Despite being an effective and a general method to obtain optimal solutions, topology optimization generates solutions with complex geometries, which are neither cost-effective nor practical from a manufacturing (industrial) perspective. Manufacturing constraint techniques based on a unified projection-based approach are . Top3d is an efficient 3D topology optimization program written in Matlab.
