| Abstract Scope |
We explore the mechanical behavior of additively manufactured topologically interlocked tessellations under bending and tensile loads. Topologically interlocked assemblies have a long history in architecture and provide unique properties, where an assembly of tiles is held in place by a peripheral force with no adhesive between neighboring pieces. We explore a special class of such assemblies composed of space-filling tiles, i.e., tiles with no empty space between any neighbors. Printing a system of such tiles results in a part that is strategically fractured to enable high energy absorption as determined by the area under the force-displacement curve. We hypothesize that increasing the intensity of interlocking will lead to higher energy absorption. We present a preliminary experimental study to test this hypothesis wherein we found that various topological interlocking methods allow for tuning of mechanical response under bending loading; by changing a few parameters, the flexural strength and ductility can change. |
