Outline of Research at the Start

The goal of this research is to investigate the influence of latch morphology and orientation on the structural integrity of biological spring and latch mechanisms using the hyperdiverse trap-jaw ant genus Strumigenys as a model. Using a pre-existing MicroCT dataset of the jaw and latch morphologies of Strumigenys ants I will use finite element analysis to simulate loads on latched jaws at various angles to test for tradeoffs between jaw gape and the structural performance of the jaws and latching mechanism.
