Lattice Structures

Research Outline

The trend of lightweighting in many industry sectors leads to the need to balance reduced material mass with structural integrity. An important class of material often used for lightweighting is cellular solids. Their high strength and stiffness at low density offer a significant advantage in structural design. These materials can be manufactured as ordered trusses or as materials (lattices) with a less ordered structure. The drawback of lattice structures is the presence of geometrical flaws, which can affect its bulk mechanical behaviour. This research focuses on the understanding of fracture of lattice structures and its sensitivity to geometrical imperfections, through a combination of topological optimisation, experimental characterisation of mechanical properties, theoretical modelling of damage mechanisms, and materials design.

About Melle Gruppelaar

Melle graduated in Mechanical Engineering in 2015 from the University of Coimbra (PT), where he performed research on Fatigue of Friction Stir Welded T-joints in AA5083. He has worked as a Simulation Engineer at Matereo before joining UCL Mech-Eng in 2018. The goal of his project is to obtain an understanding of the interaction of damage mechanisms at multiple length scales, and to develop guides on fracture design for cellular materials/lattice structures.
