Tribomechadynamics Lab, Prof. Matthew Brake Published journal papers, presented at conferences, utilized Rice University high performance computing, taught numerical techniques to graduate students, instituted unit testing and project GitHub repositories, applied nonlinear finite element models. Modeling Modal Interactions: Used Python to code harmonic solution techniques for nonlinear vibration, successfully developed method for tracking nonlinear vibration phenomena (superharmonic resonances) with reduced computational cost. Physics-Based Friction Modeling: Developed friction model based on tribology and microscale contact for bolted joints, significantly improved the models’ capability to capture experimental behavior, incorporated model aspects from literature. Empirical Friction Modeling: Implemented friction models and analytical gradients, optimized parameters for dynamic bolted joint model to analyze model form error, increased understanding of important friction model features, collaborated on optimization framework for simulations.
