Insect body and limb segments are connected using internal, soft membranous and external hard materials of varying geometries to allow for motion whereas vertebrates employ internal stiff and soft components with physical constraints. Insect joints are therefore mechanically distinct from vertebrate joints. Ants, in particular, have a highly integrated system that is comprised of composite materials, internal muscle mechanisms, and material microstructure. As a result of their unique structure and material properties they are able to carry loads in excess of 1000 times their own weight, the load path of which passes through the neck joint. To study this joint, multiple experiments were conducted prior to this research project using a custom-built, open centrifuge following a method also used to investigate the attachment forces of arboreal ants. The current project builds on the results obtained from the previous project, including the development of a device for a neck joint tensile test. This improved design involves a load cell and a displacement sensor that record the load and displacement values when the neck is being loaded to the point of failure. These values are then used to determine the stress and strain values and compared to the values obtained in the previous research. The design of the tensile tester also includes the design of a fixture for holding the ant without compromising its internal structure and geometry.
