Track model for predicting dynamic responses of railroad bridge approaches
… study focused on the development of a novel train-track-bridge model that can analytically tackle the difficult problem of a railway track transition zone and effectively simulate the dynamic response of a bridge approach subjected to moving train loads. The scope of the research encompassed …

Modeling Vehicle and Rail Vibrations Due to the Passage of High Speed Trains Using Coupled Traveling and Stationary Finite Element Models
… on the effects of incorporating high speed trains into existing rail infrastructure. Simulating vibrations through rail and soil substructures is a complex task, and has been the subject of research for decades. As computational technology and dynamic modeling theory develop, the potential …

Rigidity of length functions over strata of flat metrics
In this thesis we consider strata of flat metrics coming from quadratic differentials (semi-translation structures) on surfaces of finite type. We provide a necessary and sufficient condition for a set of simple closed curves to be spectrally rigid over a stratum with enough complexity, extending a …

Ground vibration from underground railways: how simplifying assumptions limit prediction accuracy
… simulate the dynamic interactions between the train, track, tunnel and soil resulting in numerical models which can predict ground-borne vibration around the tunnels and at the soil surface. However, all such numerical models rely on simplifying assumptions to make the problems trackable: soil …
