Topology optimization of structures with metamaterials – Presented by Jun Wu, TU Delft

Jun Wu, TU Delft, will speak at 4D Printing & Meta Materials Conference, on April 17, during the 3D Printing Event in The Netherlands.

Lightweight structures are of ultimate importance in aerospace, automotive, and industrial design engineering. Typically structures are designed and manufactured with solid materials. Emerging porous metamaterials offer new opportunities and challenges for the design of functional structures.

In this talk I will highlight some of our research on topology optimization of engineering structures that are composed of metamaterials.

The first approach, inspired by trabecular bone, generates porous bone-like infill structures. These structures are lightweight and robust.

In the second approach, we design functionally graded metamaterial with ensured connectivity between adjacent unit cells. This is applied to the design of orthopedic implants.


What drives you?

To share knowledge and explore collaboration opportunities

Why should the delegate attend your presentation?

There is a gap between metamaterial discovery and structural optimization. My presentation highlights latest academic research that aims at bridging the gap.

What emerging technologies/trends do you see as having the greatest potential in the short and long run?

Integrated design of structures and materials

What kind of impact do you expect them to have?

Lightweight structures with optimal performance. In aerospace and automotive engineering, a reduction in operational cost and less emissions of greenhouse gases. In biomedical engineering, increased functionality and longevity of implanted devices.

What are the barriers that might stand in the way?

Lack of multidisciplinary joint efforts, and between academia and industries

About Jun Wu

Jun Wu is an assistant professor of Design Engineering at TU Delft. Before this, he was a HC Ørsted postdoc fellow at the Section of Solid Mechanics, TU Denmark. He obtained his PhD in Computer Science in 2015 from TU Munich, and a PhD in Mechanical Engineering in 2012 from Beihang University, China.

His research focuses on computational design and fabrication, exploiting the unprecedented design freedom offered by additive manufacturing (3D printing) to facilitate the design for the best performance. Exemplary topics include:
(1) Design of medical devices with tailor-made physical properties,
(2) Design of soft-bodied robots for stable physical interaction,
(3) Design of lightweight and robust structures for 3D printing.

Underlying such diverse design problems is computer simulation and optimization (e.g., topology optimization) of shapes, structures, and (meta-)materials. It builds upon and extends the state-of-the-art in computer graphics, computer-aided design, and computational mechanics, and in particular regarding geometry and physics.
