Micro Abstract:
Sea urchin spines show a complex hierarchical lightweight structure which consists of porous calcium carbonate. They can resist high mechanical loads and when getting compressed, they show a graceful failure behavior. Numerical analysis starts with generating models of sea urchin spine parts based on CT-images. The second approach is based on parametric modelling, to create cellular solids with varied parameters. These are then used in simulations to analyze the influence of the microstructure.
