Explaining and Exploiting the Resistive Force Theory - Toward Optimal, Flexible, Locomotor Designs
Abstract
This proposal seeks to probe the fundamental underpinnings behind the successful Resistive Force Theory (RFT) for mobile intruders in granular media. The Pl will approach the objective by conducting a systematic set of continuum simulations to identify the degree to which the RFT hypothesis emerges from better-understood constitutive models for bulk granular media (e.g. continuum plasticity with friction-based yielding). In particular, the PI will test the RFT superposition principle against full-field numerical solutions using the Drucker-Prager and other frictional plasticity models. This will allow the PI to reconcile RFT superposition through the hyperbolic character of the model-reduced plasticity equations.
